* 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 have many other styles of sieve bras, but this one is absolutely my favorite! It fits perfectly with no bulges and is fully adjustable. The thin straps allow me to wear it with almost all of my sleeveless clothing.
