* 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.

Sieve Non-Wire Bra in Coral
Rated 5 out of 5 stars
Incredible
This might be the most comfortable bra I’ve worn. And with the comfort comes support. I have a naturally large chest, and this bra held everything in place while still giving a nice shape—no dreaded “uniboob.” Very breathable, too.

So Comfortable
This is my first time trying Negative Underwear, I am so glad I did. I was looking for a bra that was comfortable and felt as if I was braless. This comes very close.

Looks great!
Got it for the wife. It looks good and she doesn't complain about it. Only drawback is the light color tends to get discolored around the armpit area, but the fabric responds well to Oxiclean.
