So sexy

Love it, the only thing I’d change is the tightness of the band on the 2

It's All That!

This is one of the most comfortable bras, with no itchiness along the straps or hook areas. It seamlessly covers the chest, literally, it has no seams and clothing looks great over it.

Sexy in Red

My wife and I both love these bras from Negative Underwear. They balance comfort and sexy all at the same time. We have gotten at least 4 different colors. Have to say the red adds a bit of fun to the mix!

Non-Wire Bra Sizing

Non-Wire Bra Sizing Size Chart

* 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
