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.

Sieve Non-Wire Bra in Buff
Rated 5 out of 5 stars
Supportive & comfortable
This is the bra I’ve been looking for. Supportive & comfortable without wire or straps cutting in anywhere. Highly recommend for bigger chests looking for something like a bralette but with actual support. I got the white in 2 and the buff in 2+. I like the support of the 2+. But the straps are thicker and there is extra fabric on the side for support. The support is good but this makes it a little cute than the regular sizing …

Great bra!
Great bra - the nude color works well under white tops and is still a sexy nude

* 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
