Great! So you've found the most gorgeous piece of lingerie, but you're not sure which size will fit you best? Fear not! Simply take your measurements and check with the sizes in the table below.

Like other leading stores, we don’t accept returns on lingerie.

We want you to be happy when you receive your goods! If you are still unsure, simply drop us a line to check on sizing and fit. We're happy to help!
