The swim scene has come a very long way. Where itty-bitty string bikinis were once de rigueur for looking sexy at the beach and by the pool, we’re now opting for on-trend bathing suits that don’t show off too much skin and rather show off just enough. To prove it, we’re calling out the Goldilocks of swimsuits: one-pieces of the low-back variety. High upfront (to avoid any wave-induced slippage) and low in the back, these pieces officially end the days of compromising coverage for sex appeal.
