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.

    Tight fit

    I took the measurements but unfortunately this was incredibly small. Had to return unfortunately. However, I liked the look so much, I ordered the next size up. Waiting for the larger size to arrive.

    Nice but

    Very nice bra. I want to love it but it’s a little tight in the cleavage area, makes it look like I have 4 boobs.

    Best Bra, two years later.

    I bought the non-wire set two years ago. I wear those two bras most days, they’ve withstood an unbelievable amount of wear. Unfortunately for me, I haven’t been able to afford to buy a new set since I’ve fallen on harder times financially, but these bras are still going strong, making my situation that much more livable. The only thing I can’t do in them is go for a run.
