One-Piece Swimsuits Eclipse Bikinis in 2017: Data-Backed Beachwear Shift

Summer is heating up, and shoppers are snapping up swimsuits online and in stores. This year marks a turning point: for the first time in decades, the classic bikini is being overshadowed by the one-piece swimsuit. Fueled by Instagram trends over recent months, this shift is confirmed by retail analytics leader Edited. Compared to the same period in 2016, one-piece swimsuits on fashion sites surged 20%, while bikinis declined 9%.

Sporty One-Pieces Take the Lead

These swimsuits are now selling three times faster than last year, per Shape magazine—from 106 days online to just 37 days on average. Demand spikes for simple, functional styles from athletic powerhouses like Speedo, Nike, and Arena. Women prioritize comfort over aesthetics (and perfect tans). Bikinis remain beach must-haves, but this one-piece resurgence means more stylish options for everyone. Ready for vacation?
