Shocked and in Love

I have a very large bust but am otherwise petite - it is extremely difficult to find bras that fit. I’m working from home now, so I am always in soft sleeping bras that are always too small. I kept seeing these on lists for large busts and decided to just try it out. WOW - these are absolutely perfect for me! If you are large chested, these are a MUST.

Non-Wire Bra Sizing

Non-Wire Bra Sizing Size Chart

* 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
