Cool, breezy, and cute all summer long

Some days it's too hot to think about what to wear.

You want something soft. Something easy. Something that looks cute even when you're just at home.

That's this dress. The open back with a soft drawstring tie lets the breeze right through. It floats over your body — never clingy, never stuffy.

Throw it on and go. No fussing. No sweating. Just easy summer.

One of our top-reordered summer dresses

Stays cool even on 90° days
The open back and loose A-line shape let air move around you. No sticky, no clingy — just breezy from morning to night.

Throw it on in 5 seconds flat
Spaghetti straps slip right over your head. No zippers, no buttons, no tugging. Ready before your coffee is.

Flatters every body shape
The flowy A-line skims your waist and hips without hugging anything tight. You look soft and put-together, not boxy.

Goes from home to errands to dinner
Add sandals for grocery runs. Add heels and gold hoops for date night. One dress, six colors, endless ways to wear it.

Soft drawstring back you can adjust
The tie at the open back lets you set how loose or snug it sits. Quietly pretty from behind — no awkward gaps.

Frequently asked questions

Can I wear a bra with the open back?
Yes — many wear it with adhesive bras or strapless bras that sit low. The drawstring tie also helps adjust how revealing the back sits.

Is the fabric see-through in lighter colors?
The fabric is lightweight but lined enough to wear without worry in white and light colors. We recommend nude-toned underwear for the lightest shades.

Does it run small or big?
It runs a little snug, so we recommend sizing up one for the relaxed drape you see in the photos.

Is it good for taller women?
The dress hits around the knee on most women 5'4"–5'7". If you're 5'8" or taller, it will sit higher on the thigh — still cute, just shorter.
