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
(

destination names like Positano and Punta del Este. ($25, Eres stores;
