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.

The swimsuit you'll actually want to wear
You step onto the sand. Skirt flowing. Waist defined. Tummy covered.
No tugging. No cover-up tied around your hips. No sucking in.
The halter top with sweetheart drawstring and A-line skirt with matching patterned hem does the work for you—nips the waist, floats over the tummy, and skims the thighs.
It feels feminine. Pretty. Like you again.
Ready to wear—just slip it on and head out the door.
Over 12,000 women chose it this summer
✓ Covers where you want, flows where it should
The A-line skirt floats away from your tummy and thighs—giving full coverage while still looking like a dress, not a tent.
✓ Sweetheart halter lifts and holds
The drawstring bust and halter ties create lift and support so you skip the separate bra. Adjustable straps fit petite to curvy.
✓ Dries in under 10 minutes
Quick-dry swim fabric resists chlorine and dries fast—so you stay comfortable from pool to beach walk to lunch.
✓ The detail that makes it look expensive
The patterned hem trim matches the bodice print—the small detail that turns a swimsuit into something you'd actually choose to wear.

Frequently asked questions
Is the bust supportive enough to skip a bra?
Yes—the halter ties and drawstring sweetheart bust lift and hold most B/C cups comfortably. Larger busts may add a swim bra for extra support.
Will the skirt ride up in the water?
No. The skirt is sewn to fitted swim shorts underneath, so everything stays in place even when swimming.
How does the sizing run?
It runs slightly small. We recommend sizing up one for the flowy fit shown in the photos.
Is it see-through when wet?
No. The swim fabric is fully lined and stays opaque wet or dry.
