Rio Top - Island Bloom

A timeless underwire silhouette, thoughtfully refined.

The Rio Top has been part of the Sienna Swim collection since the very beginning. For The Summer Edition 2026, we've introduced four new prints and colors, bringing fresh life to one of our longest-standing silhouettes.

Designed with supportive underwire cups, adjustable shoulder straps, and adjustable back ties, the Rio creates a flattering, feminine shape while remaining comfortable enough to wear all day. It's the kind of classic you'll reach for season after season.

Named for the people and culture of Rio de Janeiro, Brazil, where confidence, color, and a celebration of the female form continue to inspire us.
