Such a lovely dress. It’s light, comfortable and the fit is really flattering. I wore it out for lunch with friends and had so many compliments.

Finally, a swimsuit you'll actually look forward to
You know that moment — walking across the pool deck, wishing you had something to wrap around your waist.
The Rivvana already has it built in.
Its side-tie sarong skirt drapes over your hips and thighs like a little dress, so you get real coverage that looks like a style choice.
Soft, stretchy fabric moves with you in the water and dries fast after. One piece. Nothing to fuss with. Just slip it on and go.
One of our fastest-moving summer styles this season
✓ Walk the deck without a cover-up
The sarong-style skirt drapes right over your hips and thighs. No extra layer needed — the coverage is built in.
✓ Stays put in the water, not just poolside
Reinforced straps and a snug bodice keep everything in place while you swim. The side tie stays knotted — no surprise undoing mid-lap.
✓ Dries in minutes, not hours
Quick-dry polyester blend means you go from the pool to lunch without sitting around in a wet suit. Comfortable in and out of the water.
✓ 6 prints that actually flatter
From bold florals to solid black, every colorway is designed to draw the eye to the right places. Not just "available in multiple colors" — each one is intentional.

Frequently asked questions
Is the skirt attached or separate?
Fully attached. The sarong skirt is sewn into the one-piece, so there's nothing extra to keep track of. Just one piece to put on.
Will the lighter prints be see-through when wet?
The polyester-nylon blend is opaque when wet across all colorways. No liner needed.
Can I actually swim in this or is it just for lounging?
Both. The snug bodice and reinforced straps are built for real swimming. The skirt flows naturally in water without dragging or riding up.
How do I pick my size?
Use the size chart below and measure your bust, waist, and hips. If you're between sizes, we recommend sizing up for the most comfortable fit.
