Got the + 1 according to the size chart. I am a petite with a G-cup. This was waaay too small for me around the band. The band size was even small for my petite C-cup daughter! I am still trying to decide if I like these bras. This company sells itself on being different but perhaps only if you are a A-B-C cup with a regular band size. Anything really different and you are out of luck!

* 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
