Popsugar Fashion Summer Fashion Sexy One-Piece Swimsuits to Buy For Summer 2021 Fancy a One-Piece Swimsuit? We Found 13 Sexy Suits to Buy For Your Shot Girl Summer 9 June 2021 by Kara Kia Image Source: Frankies Bikinis As POPSUGAR editors, we independently select and write about stuff we love and think you'll like too. If you buy a product we have recommended, we may receive affiliate commission, which in turn supports our work. Pamela Anderson's red one-piece swimsuit from Baywatch continues to be the little black dress of swimwear. And while a high-leg swimming costume is a sexy and sophisticated choice for the seaside, we also appreciate that it helps us to feel more body confident after a year of living in elasticised waistbands. For summer 2021, our favourite swimwear brands are sustainably made and independently owned. Kai Collective, launched by British entrepreneur Fisayo Longe and loved by I May Destroy You star Michaela Coel, is creating some of the coolest suits for the summer in the brand's signature prints. We're also loving celebrity-favourite brands like Heart of Sun, Frankies Bikinis, and Hunza G that are often worn by Bella Hadid, Naomi Osaka, and Kylie Jenner. For sustainable options, we suggest checking out Weekday for size-inclusive suits that go up to a UK22, Reformation for more classic pieces, and Rixo for the brand's colourful, vibrant prints.
