Beautiful and comfortable. This style will be great under racer back tanks and t’s. Very glad I gave it a try. Love the color. Wish they would offer a bikini/brief style in this color. Tried the thong…but am not a fan of that style. I like my bras and underwear to match. (Found some workable options at VS … ) Actually, would love if they offered ALL of the Whipped line in Glacier as well. The Whipped Henley and Cardigan are such amazing pieces. I own them in all the colors offered and would buy them in Glacier and Babe in a heartbeat if they were average. Thanks Negative for amazing products that are comfortable, beautiful, feminine and soft!

Non-Wire Bra Sizing

* 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
