The Open-Back Dress You'll Live In All Summer
You know the dress.
The one you reach for when it's too hot to think about an outfit. Throw it on over a swimsuit, knot the back, walk out the door.
LunaVibe™ Backless Cami Dress is that dress — easy and relaxed from the front, quietly striking from behind.
An Open Back That Does All the Talking
The front keeps it simple — a soft scoop neck and thin straps that sit easy on the shoulders. The back is where it gets interesting: a deep scoop open back with a delicate self-tie you can loosen or cinch to sit exactly how you like.
Soft crinkle fabric. No ironing. Ready to wear the moment it lands.
✓ THE OPEN BACK IS THE WHOLE POINT: A plunging scoop back with an adjustable tie reads bold from behind while the front stays relaxed and breezy. Effortless going in, head-turning walking away.
✓ CRINKLE FABRIC, ZERO IRONING: The textured crinkle weave is made to look lived-in. Pull it out of your bag, shake it out, wear it — no steamer, no fuss, no creases to worry about.
✓ ROOM TO MOVE IN EVERY DIRECTION: The relaxed, flowy cut skims your shape instead of clinging to it. Cool on hot days, comfortable from beach to dinner, flattering on every body.
Crinkle Fabric That Skips the Iron
The lightweight crinkle texture is the secret here. It's breathable enough for the hottest afternoons, and the natural crinkle means it never needs pressing — it's supposed to look soft and a little undone.
Pack it, ball it up in a tote, pull it out at the hotel. It comes out looking exactly the way it should.
One of Our Most-Loved Summer Dresses This Season
It's become a warm-weather staple for a reason — easy to wear, easy to pack, and it works whether you're heading to the beach or out to dinner. The kind of dress that quietly becomes the one you keep grabbing.
Easy From Morning to Evening
✓ Beach to dinner in one layer: Over a swimsuit by day, with sandals and gold jewelry by night. Same dress, two completely different looks.
✓ Travels flat, wears fresh: Light, soft, and wrinkle-friendly — it tucks into any bag and comes out ready to go.
✓ Flattering on every figure: The flowy, oversized cut wraps around you without pulling or clinging, so it moves with you all day.

Curious? Here's What You're Wondering
How do I pick my size?
We recommend going one size up from your usual US size. Our pieces run snug, and the next size up gives the roomiest, most true-to-photo drape. The adjustable back tie lets you fine-tune the fit from there.
Is the fabric thin or see-through?
It's a light, breathable crinkle fabric built for hot weather. Lighter shades can read slightly sheer in direct sun, which makes it a great beach cover-up — easy to wear over a swimsuit or with simple underthings underneath.
How does the length hit?
It falls around the knee on most people — long enough to feel like a dress, short enough to stay breezy. Our model Lola is wearing a size S in the photos.
Is it really good for both beach and evening?
Yes. Throw it on over a swimsuit with flat sandals for the day, then add heels and jewelry for dinner. The open back makes it feel dressed-up without any extra effort.
Will it wrinkle or need ironing?
No. The crinkle texture is designed to look soft and relaxed, so it resists wrinkles naturally — pack it, travel with it, and skip the iron entirely.
