Sizing is tricky - every body is different, and swimwear is less forgiving than most clothes. This guide reflects our fit as accurately as we can make it, but treat it as a starting point: some styles run slightly different, and individual product pages note when they do. In doubt between two sizes? Email us at hello@ohoyswim.com and we will help you choose.
