Alexa Bikini Top

Founded in 2009 by Carl Cunow and Nathan Romano, Onia's range — from basics to beachwear — is designed for ease with clean-cut silhouettes and high-quality fabrics to create a reliable wardrobe for every day.

A fresh take on a classic string bikini, the Alexa Top features triangle cups that slide along the band for more or less coverage, adjustable straps and a tie that fastens in the back.
