About Whistles
Whistles is a British contemporary womenswear brand founded in 1976, headquartered in London. The brand designs modern womenswear with a refined, considered aesthetic — clean lines, neutral palettes, and elevated everyday pieces designed to span work, evening, and weekend wear. Whistles's product range covers tailoring, dresses, knitwear, denim, blouses, jumpsuits, outerwear, and accessories, with the brand particularly known for its modern tailoring, well-cut trousers, and the consistent quality of its core wardrobe pieces. The brand operates UK retail through standalone stores in London and other major cities, alongside whistles.com. Whistles's positioning sits in the contemporary upper-mid market, between high street and designer, appealing to working women in their 30s–50s seeking elevated, modern British clothing. Whistles deals typically appear in dedicated end-of-season sales, mid-season promotions, and Black Friday events.
