Uses the European sizing system. This brand makes cups C, D, E, F, G & H. Cups run about one cup size large. Visit our FAQ to find your equivalent cup size in other sizing systems. If you aren't sure of your size, please give us a call and ask us to look up your previously purchased bra sizes. If you have never been fitted with us before, make an appointment for a fitting or arrange for a virtual fitting with one of our expert fitters. Click "Appointments" at the top of this page or give us a call. When the bra is new, it should fit you snugly but comfortably on the loosest hook. This will ensure that you can get your money’s worth out of the bra. After you’ve had the bra for a while, the bra will stretch out, and you can begin to wear it on the middle hook, then eventually on the tightest hook.
