Should’ve bought sooner!

I looked at this bra a few times before making a purchase. Now I’m wondering what took me so long. This is the only bra I need in my life. For reference (simply because I always find it helpful) I’m usually a 30B, went with Size 1, and hook it on the tightest setting.

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
