Sunscreen—as well as a jiggle-free body—may be the most obvious pairing with your favorite bikini, but this spring, swimwear makes a nice match with less utilitarian bedfellows. Long the go-to for elegant maillots, Eres is introducing a trio of limited-edition nail polish hues: Yellow Soufi, Rose Bengale (below, right), and Brown Damas, which conveniently correspond with three of the label’s suit colors.
Meanwhile, Prism eyewear founder Anna Laub has launched a line of Old Hollywood–worthy suits to complement her hip shades. Bandeau tops (above, left), string-tie styles, and strapless one-pieces have catchy destination names like Positano and Punta del Este. ($25, Eres stores; $80–$275, prismlondon.com)
