Our best selling bra for a reason.


The most supportive of our wireless bras. Great shape, naturally smoothing, airy light and sexy sheer — Belgian micromesh might just be magic.

    My favorite bra. I am supported and don't feel like I am wearing anything, even in the SC heat. That is saying a lot for someone who is a DD.

    As good as everyone says!

    Nothing more to add except that this IS the perfect bra. Only problem is that now I have to get rid of everything else bc since ordering this and the Whipped non wire and the Sieve Bra top, I haven’t reached for anything else. If you’re on the fence, JUST GET IT.

    Almost Perfect

    Incredibly comfortable, when I’m wearing my other bras I really notice how much better the comfort is here. I do find it slightly flattening but am looking forward to having for the summer months. I do wish negative offered an even slightly lined wireless option.

    Love!

    My expectations were low and I was honestly so impressed the first time I tried this bra on. It's comfortable, supportive, and my nipples remain hidden under most tops (white, being the exception). Highly recommend!

    Amazed!

    Amazed that a mesh bra could be supportive, yet comfortable. I was worried about my nipples being too exposed, but honestly it has not been an issue at all (with the exception of a white shirt).
