The only dress you can bear when it's 30°C.
Loose. Open-backed. No waistband. Fully opaque — wear it braless.
The problem with every other backless dress
- It’s see-through in daylight. You find out at the worst possible moment.
- Bra? Tape? Nothing at all? Every other backless dress leaves you to work it out — and to pay for it.
- It clings, and it creases. One wear and it looks slept in.
- It stops at a size 16. Or fits nowhere past it.
The Effortless™ fixes all four.
One dress. Everywhere you're going.
Beach to dinner, city to sofa — one throw-on, every plan.

I was looking for the perfect summer dress, and this is it. It’s incredibly comfortable and soft, with a fluid drape that flatters without clinging. The open back adds a lovely, quietly sensual touch, and it’s wrinkle-free straight from the bag. I’m already planning to get more colours.
"It's 30 degrees and I'm not giving up the comfiest thing I own just because my husband can't behave himself 🙈 5'4, took the S, comes right to my ankles."
Je l'adore ! J'avais un peu peur de la qualité du tissu mais c'est génial coton + polyester, juste ce qu'il faut. Elle ne se froisse pas. Elle est légère, agréable. Elle reste bien en place malgré l'ouverture dans le dos. Le reste fait son effet !

"Took two away with me and wore nothing else for ten days. I'm 5'10 so I went for the L and it still sits right at the ankle. Beach in the morning, dinner in the evening, folds down to nothing and doesn't crease. My friend ordered one from the sunlounger next to me. That's the review, really."
Love this dress SO comfy, yet stylish, wore it on the beach then at the airport..Would DEFINITELY buy again+can highly recommend..
"Ten days away and I wore these two dresses and almost nothing else. Straight over a swimsuit in the day, sandals and earrings at night. No creases out the case, not see-through in full sun. 5'6, size M. My friend ordered one from the sunlounger next to me."
Perfect for a bikini cover up, nighty or casual dress in high summer. I got the blue and it’s not see through. They are an oversized fit and the back is adjustable. I’m a size 8 and I got a small and it’s pretty big I’d recommend sizing down as an xs would have been even better. I’m 5ft2 and the length is good so wouldn’t suit taller girls. The colour is a gorgeous shade
Perfect in this weather, takes up no room when travelling..light weight comfortable and cool. Liked so much I bought 3 more. Perfect for lounging around the pool and to wear around the house, better than a louder suit which I find to warm.
Great quality. i’m 5ft 7in and it is full length on me.
Beautiful dress!! i ordered m because i am pregnant, 178 cm tall and 83 kg but i still have plenty of space in this dress, the material is pleasant and good for summer. very happy about my purchase!
Super comfortable and beautiful, cool for summer, suitable for wearing on the street as well.
