* 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

This is my correct bra size. But when I wore it last week, I was aware of lots of extra flab above the bra, under my arms especially.
I think your sizing needs to adjusted for older clients, or maybe your product isn't for older women. We've lost the subcutaneous fat we used to have so our skin sags. I'm not fat, but the bra makes me feel and look fat. My breast fit the bra's cup, but the bra itself is not designed for a 69 year old woman. I feel I've wasted my money.
