* 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

I had high hopes for this bra because it's flattering and made with quality materials. Unfortunately, the design fell short for me. The top of the T-strap sits too high—almost at my neck—and is visible with every racerback tank I tried. The elastic bottom band feels rigid and uncomfortable; a softer, more flexible band would make a big difference. For a non-underwire bra, I was expecting more comfort, especially for lounging, but it just didn’t work out. I wear a 34B and went with a size 2 based on reviews saying it runs small, but it fits nearly the same as the size 1s I already own.

Comfortable, although not super supportive for someone with 32DDD/E, but it did the job I needed and then some. Probably depends on your outfit but with the style of dress I wore, it was perfect.

This bra is gorgeous and it fits me well. However, if you are a dark skinned woman the color options are lacking. I purchased the black and the buff. Both work under dark clothing. Neither works under lighter clothing. Seeing a black or beige bra under a light colored top is distasteful. Too bad Negative doesn't think enough of all their customers to offer a couple shades of brown.
