Kastane

WHIMSIC is a unisex brand officially developed within the Kastane brand family. While Kastane’s own offerings focus primarily on womenswear, WHIMSIC handles gender-neutral clothing and fashion accessories, bringing elements of military and workwear into contemporary everyday wear. On PAL CLOSET, it is consistently presented as a separate product category under “Kastane > WHIMSIC,” with seasonal collections and a lineup including clothing, bags, hats, and sunglasses. It can be identified as a derivative line within Kastane focused on unisex everyday wear.

B Kastane is a derivative line that Kastane officially offers as its “basic line.” It proposes a “new standard” for people who, starting from fashion and culture, enjoy every aspect of their lifestyle in their own way. Unlike the seasonal offerings of Kastane’s main line, it centers on basic wear that is easy to incorporate into everyday life, and offers items such as tops, knitwear, denim, slacks, and bags. It is treated as a separate lineup on PAL CLOSET and ZOZOTOWN, as well as at select stores, and new releases have continued from 2025 through 2026.
