About Superdry

Superdry is a British casualwear brand founded in 2003 by Julian Dunkerton and James Holder, headquartered in Cheltenham. The brand is known for its distinctive blend of Japanese-influenced graphics, American vintage references, and British design sensibility — captured in the brand's signature Japanese-character branding across many of its product lines. Superdry designs menswear, womenswear, and kidswear across T-shirts, hoodies, jackets (including the brand's signature Windcheater jacket), denim, knitwear, joggers, swimwear, and accessories. The brand operates UK retail through standalone stores and partner retailers, alongside superdry.com. Superdry's positioning sits in the accessible-casual market, with strong recognition for its outerwear, graphic T-shirts, and the bold Japanese-influenced aesthetic across many product categories. Superdry deals typically appear in frequent promotional events, end-of-season clearance, an Outlet section, and Black Friday.
