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.

    Love!

    I have this in 2 other colors and tried a smaller size this time since I have lost some weight. Had to exchange for my original size but team made it very easy.

    Need one in every color

    The Sieve Non Wire Bra is my favorite. So comfortable and moves with me. Doesn’t roll up. I’m mid-sized and it fits so well. Just bought my second color.

* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.

Btw, the size nomenclature has changed for Bra Tops. Here's the conversion:
XS=0, S=1, M=2, L=3, XL=4, XXL=5
