Oséree - Oséree's cobalt-blue bikini is aptly named Lumière, which translates as light in French, nodding to the label’s signature sparkling jersey. It’s crafted in Italy to a minimalist silhouette with a one-shoulder top that’s lightly boned at the sides with soft cups, while the triangular briefs are shaped with skinny side straps. Wear it on your next vacation for a glamorous poolside edit.
