All the comfort, and a bare back.
No underwire digging in, no marks: just soft lace that follows your shape. "The only one I can bear to wear," Catherine told us.
It fastens low on the back, for your backless dresses, tops and bodysuits. With a back cut down to the waist, it may still show.
As a bralette under an open shirt or on its own with jeans: the floral lace and plunging neckline are made to be seen.
White, khaki green, black, red or pastel pink. "I bought it in 3 colours," Claire told us.
Your everyday bra, backless or not.
The fabric, the support, the fit: what to know before you choose.
Supple and light, with cups padded just enough: you won't feel it all day.
Ideal for cups A to C. Beyond that, the support stays light: customers with a D cup find it too snug.
From S to 3XL: find your French bra size in the guide. Between two sizes? Our customer care team will advise you.

Frequently asked questions
How low does it sit on the back?
It fastens low on the back, for most backless dresses, tops and bodysuits. With a back cut down to the waist, it may still show. Send a photo of your outfit to our customer care team and they'll tell you if Aly works.
Which size should I choose?
This style runs small: find your French bra size in the guide. S: 75-80 A/B, M: 80-85 A/B, L: 85-90 A/B, XL: 90-95 A/B or 75 C, 2XL: 95-100 A/B or 80 C, 3XL: 105 A/B or 85 C. Not sure? Our customer care team will help you choose.
Does it give support without underwire?
Yes, for a small to medium bust: the lace and lightly padded cups follow your shape. From a D cup up, the support stays light.
Can I wear it on its own, as a top?
Yes, that's one of its strengths: as a bralette under an open shirt or on its own with jeans, the floral lace is made to be seen.
Which colour should I choose?
The white is a creamy white. Pastel pink stays discreet under light dresses: "in powder pink, it's invisible under white dresses," Kaija told us. Red, khaki and black also work as a bralette under an open shirt.
