Please keep in mind that these sizes are approximations. Since they are made by hand, each garter will vary just a little bit.
The sm/med garter is about 14-15" around. A single line garter will stretch fairly comfortably up to apx. 20" around, and the double line garter will stretch comfortably to about apx 22" around. If you are getting close to the top of the stretch, then we suggest moving up to a med/lrg size garter, just for comfort.
A med/lrg size garter is about 16-17" around. A single line garter will stretch fairly comfortably to about 26" around, and the double line will stretch comfortably to about 28" around. If you are at the top of that sizing, then let us know, and we can make a garter that stretches comfortable to you size.
We want to make sure that the garters are comfortable for you! The garters we make should feel soft on the leg, and not something that is going to bother you on your wedding day. So make sure you choose a garter size that will be comfortable.
