* 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.

My package got lost in the mail and Kiran from customer service was super quick to respond and send out a replacement! I got it within a few days. The bra itself is lovely and comfortable - a little more sheer than I anticipated, but I don't mind :) looking forward to trying more from Negative!

Lovely, lightweight, and even thought it's sheer provides good coverage under a t-shirt.

I love the sieve bra top in 2+. It is sheer, sexy and offers great support. I've tried other styles such as this in a 4 and it's a cute concept but doesn't compare. Fingers crossed that the sieve bra top will soon come in more colors in a size 2+. Very few styles come in fun colors in a 2+.
