Fabletics is expanding its approach to leggings, sports bras and cold-weather activewear through its latest collaboration with Khloé Kardashian, placing renewed attention on seamless construction, flexible fabrics, adjustable support and clothing designed for movement beyond the gym.
On September 24, 2026, the California-based activewear company introduced its eighth collection with Kardashian, continuing a partnership that began in 2023. The new release includes 19 styles, ranging from redesigned cold-weather leggings to fleece layers, jackets and accessories.
For consumers, the more interesting development is not the celebrity collaboration itself. It is how Fabletics is refining familiar activewear categories around different combinations of compression, softness, support and seasonal comfort.
The collection also highlights an important distinction: leggings and sports bras that look similar can behave very differently during exercise.
A seamless legging may reduce irritation from certain seams but still fit poorly if its waistband moves. A soft sports bra may feel comfortable during Pilates yet provide insufficient movement control for running. Likewise, a thicker winter fabric may retain warmth without being suitable for every indoor workout.
Understanding these differences can help shoppers make more practical decisions about fit and performance.
Fabletics Introduces Its Eighth Khloé Kardashian Collection
Fabletics announced the collection from its headquarters in El Segundo, California, describing the September 24 launch as an expansion of its ongoing partnership with entrepreneur and television personality Khloé Kardashian.
The 19-style release introduces several new cold-weather pieces, including the Belted Shine Insulated Coat, Teddy Hooded Jacket, Polar Fleece Cropped Hoodie and Polar Fleece Wide Leg Sweatpant.
It also updates the company’s Cold Weather line with a seamless construction appearing across leggings, a jumpsuit, a half-zip top and a shrug.
According to the company’s September 24 collection announcement, the range introduces Polar Fleece and Flutter Knit materials while maintaining a size offering from XXS through 4X, depending on product availability.
Kate Williams, vice president of women’s design at Fabletics, explained that the collaboration continues to refine garment fit, fabric selection and construction.
The company also organized a nationwide in-store promotion from September 25 through 27 and a special activation at its Century City flagship in Los Angeles on October 3 and 4.
Those events supported the collection’s retail launch, but the longer-term significance lies in the product development.
Rather than relying exclusively on new colors, Fabletics is updating established designs and introducing additional materials for different activities and weather conditions.
No-Seam PureLuxe Leggings Highlight Changes In Front-Seam Construction
One of the most recognizable products associated with the Fabletics and Kardashian partnership is the No-Seam PureLuxe TLC Legging.
The garment uses a modified front construction that eliminates the conventional center-front seam found in many leggings.
That detail matters because seam placement can influence how fabric feels during bending, squatting, walking and other repeated movements.
A prominent front seam may create unwanted pressure or friction for some wearers, particularly when a garment is tightly fitted or the seam falls in an uncomfortable position.
Removing that seam changes the way the fabric is assembled, potentially reducing one source of irritation.
However, a no-front-seam design does not automatically guarantee better comfort.
Fabric tension, crotch depth, waistband placement and overall garment proportions remain important.
According to the official Fabletics PureLuxe legging specifications, the product uses 82% polyester and 18% spandex, with four-way stretch, a soft brushed finish and targeted compression.
Fabletics also lists anti-chafe construction and a cellphone pocket among its features.
These specifications describe the manufacturer’s intended design. They do not independently establish that the leggings will prevent friction or remain comfortable for every body type.
A shopper should still evaluate how the garment behaves during actual movement.
Seamless Leggings Still Need A Stable Waistband
Seamless construction receives considerable attention in activewear marketing, but waistband performance can be equally important.
A waistband should provide enough stability to remain in place during the intended activity without creating excessive pressure.
If the waistband rolls downward during squats, shifts during running or requires constant adjustment, the leggings may not fit the wearer properly.
This can happen even when the fabric feels exceptionally soft.
The PureLuxe line combines stretch with a close-fitting silhouette, but the experience will depend on how that stretch interacts with an individual’s proportions.
Waist-to-hip differences, torso length and preferred rise can all affect whether a waistband feels secure.
For that reason, trying on leggings while standing still is only a starting point.
A more useful fitting assessment includes several controlled movements:
- Perform a comfortable squat and observe whether the waistband stays in place.
- Raise one knee toward the chest and check for pulling around the hips.
- Walk briskly or step onto a low platform to evaluate fabric movement.
- Bend forward and check whether the fabric provides the desired coverage.
- Notice whether the garment requires repeated adjustments.
These checks are not a standardized laboratory test. They are practical ways to identify obvious fit problems before committing to a purchase.
A properly fitting legging should accommodate normal movement without making the wearer continually aware of the garment.
PureLuxe Fabric Combines Softness With Stretch And Compression
Fabletics positions PureLuxe as one of its softest performance fabrics.
Its polyester-spandex composition is designed to provide stretch while maintaining a smooth, close-to-body fit.
The brushed surface is intended to create a softer hand feel, while the elastane content allows the material to extend and recover during movement.
These characteristics may make the fabric appealing for studio exercise, walking, stretching and everyday activities.
However, softness and support are separate qualities.
A soft fabric can still feel restrictive if the garment is undersized. Conversely, a fabric with substantial stretch may not provide the level of compression someone prefers for a particular workout.
Fabric weight also matters.
A lightweight legging may feel comfortable in a heated Pilates studio but provide less warmth outdoors during colder weather.
A thicker legging may feel appropriate for an autumn walk but become uncomfortable during an intense indoor training session.
The most useful approach is to evaluate the entire garment rather than judging performance from fabric composition alone.
Fabletics Expands Cold-Weather Leggings With Seamless Construction
The September 2026 collection introduces an updated seamless design across the company’s Cold Weather range.
According to Fabletics’ official Khloé Edit overview, published September 28, the collection includes cold-weather leggings alongside fitted performance layers and insulated outerwear.
This is a meaningful development because cold-weather activewear has different functional requirements from lightweight summer leggings.
Outdoor movement often requires balancing warmth, flexibility and moisture management.
A fabric that retains heat may be comfortable during a brisk morning walk but less suitable for an extended workout in a warm indoor environment.
Layering also changes how leggings perform.
A person wearing leggings beneath a longer jacket may experience different levels of warmth and airflow than someone wearing the same garment alone.
The new collection’s combination of leggings, fleece and outerwear suggests that Fabletics is treating activewear as part of a broader seasonal clothing system.
Nevertheless, shoppers should avoid assuming that every garment marketed for cold weather offers the same degree of thermal protection.
Fabletics’ announcement does not establish a universal temperature rating for the entire collection.
Weather conditions, exercise intensity, wind exposure and personal comfort all influence how much insulation someone may need.
PureLuxe Push-Up Bra Adds Adjustable Low-Impact Support
Alongside its leggings, Fabletics continues to develop sports bras with different combinations of structure, softness and adjustability.
The PureLuxe Push-Up Low Impact Bra is among the products associated with the Kardashian collaboration.
According to the official Fabletics sports bra description, the garment features a scooped V-neck, shaped underbust, removable cups and adjustable straps.
It uses the same 82% polyester and 18% spandex PureLuxe fabric composition found in the leggings.
Fabletics identifies the bra as a low-impact design, an important distinction for shoppers comparing different levels of support.
Low-impact sports bras are generally intended for activities involving less repetitive breast movement, such as gentle yoga, walking or some forms of strength training.
They should not automatically be considered equivalent to high-support running bras.
The product’s removable cups allow wearers to adjust its internal structure, while adjustable straps provide another opportunity to modify fit.
However, neither feature guarantees adequate support for every activity.
The lower band, cup fit and overall stability remain important.
Adjustable Straps Matter More Than Decorative Design
Sports bras increasingly combine functional features with fashion-oriented construction.
Crossback straps, layered panels, removable padding and shaped necklines can influence both appearance and comfort.
Yet these elements should be assessed according to their practical purpose.
Adjustable straps can help a wearer modify how a bra sits on the shoulders and upper torso.
A stable underband helps keep the garment positioned during movement.
Cup construction can influence how support is distributed.
These features are particularly relevant when comparing sports bras intended for different activities.
A bra that feels comfortable during stretching may not provide sufficient movement control for repeated jumping or running.
Likewise, a heavily compressive bra may feel unnecessarily restrictive during a low-intensity session.
Fabletics’ distinction between low-impact and higher-support products reinforces the need to match the garment to the activity.
Consumers should not interpret a push-up design, molded cup or thicker fabric as automatic evidence of high-impact support.
Compression Should Support Movement Without Creating Discomfort
Compression is one of the most frequently used terms in leggings and sports-bra marketing.
In practical terms, compression describes the pressure a close-fitting garment applies to the body.
That pressure can contribute to a secure fit, but more compression is not always more comfortable.
A tightly fitted waistband may remain stable while still creating unpleasant pressure.
A compressive sports bra may limit movement but become uncomfortable if the band or straps fit poorly.
Similarly, leggings that feel secure during standing may restrict certain movements if the garment lacks sufficient stretch or is the wrong size.
The distinction is especially important for consumers choosing activewear based on photographs or promotional descriptions.
A garment’s appearance cannot reliably establish how it will feel during exercise.
Research on sports-bra design also supports evaluating movement control and comfort together rather than assuming maximum tightness is the ideal outcome.
For leggings, the equivalent principle is straightforward: a secure fit should not require persistent discomfort.
Size Inclusivity Needs To Extend Beyond The Size Chart
Fabletics says the September 2026 collaboration is available in sizes ranging from XXS to 4X.
A broad size range can improve access to activewear, but inclusive sizing also depends on garment proportions and construction.
Two people wearing the same nominal size may have different waist-to-hip ratios, torso lengths, shoulder proportions or support requirements.
Those differences can affect how leggings and sports bras fit.
For example, a legging may fit comfortably around the hips but feel loose at the waist.
A sports bra may provide enough cup coverage but have a band that shifts during movement.
These are garment-fit issues, not problems with the wearer’s body.
Fabletics’ expanded sizing is therefore a useful starting point, but shoppers still benefit from checking individual product measurements and fit guidance.
The company’s No-Seam PureLuxe TLC Legging listing includes different inseam options, which may help accommodate variation in leg length.
Even so, availability can vary by color, size and style.
A larger size range does not eliminate the need for careful fitting.
Matching Sets Are Convenient, But Leggings And Bras Have Different Jobs
The latest Fabletics collection continues the popularity of coordinated activewear sets.
Matching leggings and sports bras can simplify outfit selection, particularly when shoppers prefer consistent fabrics and colors.
However, coordinating pieces do not necessarily provide the same level of functional performance.
A soft legging may be appropriate for several activities, while a matching low-impact bra may not provide enough support for running.
This distinction matters because consumers sometimes purchase coordinated sets without evaluating the garments separately.
A more practical approach is to choose each piece according to its function.
For leggings, relevant considerations include waistband stability, coverage, stretch, seam placement and temperature comfort.
For sports bras, support level, band fit, strap adjustability and movement control may be more important.
Matching colors can be a preference, but they should not determine whether the clothing is appropriate for the workout.
What Shoppers Should Check Before Buying Fabletics Activewear
The September 2026 collection gives consumers several construction features to compare, particularly within the PureLuxe and Cold Weather ranges.
The following distinctions can help organize those choices.
| Design Feature | Potential Practical Benefit | What Shoppers Should Verify |
|---|---|---|
| No-front-seam leggings | May reduce pressure from a center-front seam | Overall fit and comfort during bending |
| Four-way stretch | Allows fabric movement in multiple directions | Recovery and coverage during squats |
| High-rise waistband | May provide a more secure feeling | Whether the waistband rolls or shifts |
| Brushed PureLuxe fabric | Softer surface texture | Comfort during longer workouts |
| Adjustable sports-bra straps | More control over strap positioning | Band stability and appropriate support |
| Removable bra cups | Adjustable internal structure | Cup fit and movement control |
| Cold-weather seamless leggings | Additional seasonal clothing options | Warmth, breathability and activity suitability |
Another consideration is how the garments are sold.
Fabletics uses both member and non-member pricing, with some promotions connected to its VIP membership program.
Shoppers should review the full purchase terms, including recurring membership charges where applicable, rather than comparing only the advertised promotional price.
The company also describes a 30-day fit guarantee on certain product pages, subject to its return conditions.
These details can influence the actual value of a purchase as much as the fabric or design.
Fall 2026 Activewear Is Becoming More Specialized
The Fabletics and Khloé Kardashian collection reflects a broader movement in activewear design toward garments intended for different environments, activities and comfort preferences.
The new release does not establish that one particular legging or sports bra performs better than competing products.
What it does demonstrate is continued investment in construction details such as seamless panels, flexible fabrics, adjustable support and seasonal layering.
For consumers, that specialization creates more choices but also requires more careful evaluation.
A no-front-seam legging may be preferable for someone sensitive to pressure from conventional stitching. Another wearer may prioritize a firmer waistband or a different inseam.
A low-impact sports bra may feel comfortable during studio exercise, while someone who runs regularly may need a more structured support system.
The important point is that activewear should accommodate the wearer’s movement, activity and comfort preferences rather than require the wearer to adapt to an uncomfortable garment.
What Fabletics’ Latest Collection Means For Workout Comfort
Fabletics’ September 24 launch places leggings, sports bras and cold-weather layers within the same evolving product strategy.
The company’s emphasis on PureLuxe fabric, no-front-seam leggings, adjustable bra construction and redesigned seamless winter garments provides several useful examples of how activewear brands are modifying established products.
Yet product features should not be confused with guaranteed performance.
A seamless construction can change where friction occurs, but it does not eliminate every potential fit issue.
Adjustable straps can improve customization, but they do not turn a low-impact sports bra into a high-support running bra.
Additional warmth can make leggings more comfortable outdoors, but the same fabric may feel unsuitable in a heated gym.
For shoppers considering Fabletics’ fall 2026 collection, the most reliable approach is to evaluate garments individually, test movement where possible and prioritize comfort over appearance-based marketing.
The strongest activewear design is not necessarily the tightest, softest or most elaborate.
It is the design that stays in place, supports the intended activity and allows people to move comfortably without unnecessary distraction.
