Kith

A derivative line focused on an even younger age group (babies) than Kith Kids, offering a structured range of apparel and accessories under the Kith Baby name. Centered on baby-specific items such as bodysuits, coveralls, and sets, its product design also takes gift demand into account, supporting Kith’s “family-oriented” offering. While Kith Kids covers a range centered on kids and toddlers, Kith Baby serves newborns and infants, separating the lines by age to make its offerings more precisely targeted.

A food and dessert offshoot brand developed by Kith to expand the in-store experience, it launched in 2015 as Kith Treats. It operates within Kith flagship stores and at some standalone locations. In addition to serving a menu, it has continued to offer merchandise featuring the Kith Treats logo, including apparel capsules, since 2017. This supports its standing as a sub-line rather than merely an in-store facility. While Kith Women, Kith Kids, and Kith Baby are offshoots organized by apparel audience, Kith Treats strengthens the brand experience through “food” and limited-edition products.

A women-only derivative line launched by Kith to expand into womenswear beyond its primarily menswear-focused offering. It began its women’s collection in 2015 and has since continued to release seasonal collections, accessories, and more under the Kith Women name. In recent years, it has operated with greater independence within Kith, notably opening a standalone women’s flagship store and appointing a dedicated creative director. Unlike Kith Kids and Kith Baby, which are derivatives organized by age group, Kith Women complements the lineup along gender lines.

A kids' line that adapts Kith's worldview and signature elements for children. Released under the Kith Kids name, it spans year-round apparel (T-shirts, hoodies, outerwear, etc.), as well as collaborations and accessories and footwear, forming the “family” segment of Kith's lineup. While Kith Women is a women-only offshoot, Kith Kids focuses on the kids' age group, with a role in differentiating sizing and uses. It also works in conjunction with Kith Baby, functioning as a core line covering the age range from babies through kids.
