* 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

Love all of Negative products and was hoping this bra would work. I am petite overall, however have a larger ribcage and unfortunately this didn't work for me.

I love my Sieve Non-Wire Bras in navy, BUT why are there so few colors in my size for months and months? I check, I check back, I get tired of looking. Please show some love to your size 3 customers. Restock! We are trying to love you back...I'd give you a five, but I'm thinking of lowering it to a three only because of the lack of availability...
