Sweaty Betty is a British activewear brand founded in 1998 by Tamara Hill-Norton, headquartered in London. The brand designs womenswear activewear and athleisure with a focus on technical fabric quality, considered design, and pieces that span performance and everyday wear. Sweaty Betty's product range covers leggings (including the iconic Power Leggings), sports bras, tops, jackets, joggers, and accessories, with the brand particularly known for its Power Leggings range, considered fabric technology, and inclusive sizing approach. The brand operates UK retail through standalone stores in London and other major cities, alongside sweatybetty.com. Sweaty Betty was acquired by Wolverine Worldwide in 2021 but continues to operate under its own name and identity. The brand's positioning sits in the premium activewear market, appealing to customers seeking elevated, technical pieces beyond mass-market athleisure. Sweaty Betty deals typically appear in regular percentage-off promotional events, end-of-season clearance, and Black Friday.
Sweaty Betty sizing generally runs true to UK standard, with the brand offering UK sizes XXS–XXL plus extended sizing on many styles. Power Leggings are designed for compressive support and run true to size, while relaxed-fit pieces (including joggers and sweatshirts) tend to fit slightly relaxed.
Sweaty Betty runs major end-of-season sales typically in late June/July and December/January, alongside recurring percentage-off promotional events, Black Friday, and a continuous Sale section featuring past-season pieces.
