01 Why We Reviewed Reasn

Reasn launched with its debut collection on 5 October (autumn 2025), founded by Adam Frisby (founder of In The Style, who stepped away from that business in 2024) and Perrie Sian, In The Style's first Creative Director. It describes itself as "a brand built on inclusivity, quality and style," with every piece in sizes 6–28, plus petite and tall options. The range includes tracksuits, leggings, cosy knits and Smoothform activewear. One example is the Smoothform Built-In Bra Sports Bra (£24.99), made of 75% polyamide and 25% elastane, with removable cups and adjustable fastenings, designed to minimise visible lines.

The honest caveats are typical of a fast-growing young brand. Most of its ~500 Trustpilot reviews came in the last 12 months, and while 89% are five-star, complaints include wrong sizes dispatched, late or missing orders, lost returns and slow replies for a minority. Trustpilot also notes the company hasn't replied to negative reviews there. The returns window is 21 days from ship date (unworn, unwashed, tags on), and UK shipping is £3.99 unless you spend £150 or more.
