Kith Women Fall Active | Proper Form

Kith Women presents its Fall 2026 activewear collection titled Proper Form, a study of movement that concentrates on elegance through the feminine form, designed to take the wearer wherever she may go throughout the day. 

Set within an ornate, Parisian-inspired interior of chandeliers, classical furnishings, and architectural detailing, the campaign places activewear in an unexpectedly formal environment, reflecting the idea that elegance, like movement, is a discipline. Through sculptural poses and refined styling, Proper Form presents a fashion-minded approach to activewear—where function and femininity move in tandem throughout the day.

The Studio and Enhance fabrications signature to Kith Women Active return this season, seen on new silhouettes such as the Halsey Halter Plunge Tank, ideal for wear during a low-impact workout or more elevated styling into the evening, the Loryn and Laenor Layered Bras, and the return of classic bottoms such as the 4” Short, 6” Short, ⅞ Legging, and Full Length Legging. The color palette for Fall 2026 comprises earth tones such as Cedarwood Heather, Caraway, and Darkshore, alongside hues from the staple Kith Palette such as Legacy, Void, and Essence. Explore staple tops in active fabrications such as the Mulberry IV, Ayven Muscle Tank, and Aryon Active Tank, alongside layerables such as the Elle U-Neck Bra, the Lowen II Nylon Track Jacket, Andrei Panelled Track Jacket, and Reyna Pleated Track Pant, the assortment rounded out by standouts such as the Aire Plunge Cross Back Romper and the Racerback Romper. 

Accessories from Kith Women Fall Active | Proper Form features upscale-yet-functional companions, designed for the Pilates studio, outdoor workouts, or everyday wear. Discover the Active Headband complete with reflective artwork alongside socks with grips at the bottom in crew and knee-high lengths, executed in colorways that match the main collection. 

To celebrate Fall Active this year, Kith Women has partnered with instructors and studios around the world to host immersive, uplifting workout classes. Starting in Osaka earlier this summer, Kith Women alongside Ami Pilates and the team at Kith Osaka and invited friends of the brand participated in a class at luxury lifestyle hotel Patina Osaka, engaging in mindful movement with the city as their backdrop. In Paris, Kith Women hosted a reformer Pilates class at Dream Seven Paris, beginning with a grounding visual meditation. Moving to London, Kith Women will be hosting another reformer Pilates class at Sunday Sporting Club, a studio that is traditionally referral-only in Marylebone, guided by their founder, Henriette Kristiansen.  

Lastly, as part of the Kith and On partnership, the K-Tech 3 is introduced in women’s sizing, utilizing Cloudzone 99 tooling, featuring CloudTec® for superior comfort, an innovative rubber outsole, and Speedboard® for added control and stability. Designed in the colorways Ivory & Storm and Black & Black, the upper is made of synthetic suede with hotmelt overlays and mesh underlays, complete with On and Kith branding at the tongue and footbed, the Kith On lockup on the lateral side, and K&K artwork at the medial side. Additionally, the previously-released K-Tech 1 & 2 get Fall 2026 color updates, Grain & Taiga and Ruby & Ox, and Shark & Ox.
