* 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

First tine for trying sieve. Nice comfortable material and the support in the triangle bra is great. I am a 36DDD and like the 4. The 5 was ok but the to use the smallest hook to tighten it up.

Love these bras! Super comfortable, probably needed to size up for cup coverage. So breathable and light. Wish they came in more colors.
