I love these bras but they have absolutely no longevity. I've tried everything under the sun to preserve the quality but they are just not built to last. The material gets stretched out no matter how carefully you hand wash them, the lighter tones become dingy and discolored, and they all lose their shape. For the price, it's just not justifiable.

Love this a little too much
I ordered a couple of Bras from Negative in 2019 and hated them; however, I saw this bra and wanted to give them another chance. I am so thankful I did! The bras are very supportive.

I find bra shopping so hard and I'm really glad I gave Negative a try. The size 1 was a perfect fit. This bra is very comfortable and the buff with black edges is so subtly sexy. I wore it with the matching thong and my husband likes them too lol.

* 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
