Fenwick
If mumsy one-pieces are your thing, avoid Princess Tam Tam. Available at Fenwick, the French lingerie-cum-swimwear doesn’t deal in frumpy currency but rather beautifully crafted swimsuits that are as flattering as they are modern. (63 New Bond Street, W1)
Heidi Klein
A favourite with the ladies who lunch in Westbourne Grove and holiday in St Kitts, Heidi Klein stocks a host of glamorous poolside offerings including its Mustique bikini and the Seychelles string. (174 Westbourne Grove, W11)
Speedo
If the task of becoming the next Rebecca Adlington figures on your checklist for autumn, Speedo’s store in Covent Garden is your one-stop shop. From Fast Skin bodysuits to punchy coloured tankinis this shop is swimming in options that are fit for a pro. (41 Neal Street, WC2)
Net-A-Porter
Our favourite luxury shopping site is a great option for those in need of a low-season swimwear fix. Stocking a host of innovative bikini brands — Mara Hoffman and Zimmermann to name a few — dear old “Net” is the ultimate for label loving (sun) loungers. (net-a-porter.com/swimwear)
Salt
This newly opened swimshop stocks bikinis and one-pieces by the likes of Lenny and We are Handsome, right. (69 Walton Street, SW3)
