I actually wore three garters!! Two on one leg and one on the other. It was a miracle that I still had circulation by the end of the night. My first on was white with blue ribbon...a
Walmart or Michaels special I think. We actually got legally married a few months ago to get the immigration process moving and this was about the only traditional piece of that wedding, so I had to wear it again. My old UK roomie couldn't make the wedding, so she sent me a really pretty white one from Marks and Spencers (which was the one I threw). When I worked at Disney, there were four of us that became best friends. For each of our weddings, we have all had a silver Mickey charm engraved with our nicknames sewn to our garters, so I had to buy a really special one to put it on. The new hubby's fav football team is Celtic and they happened to be selling a garter on their site, so I bought that. It was a nice surprise. The boys thought that they'd be smart and all wore garters for me to remove!!

The first picture is my "old" garter and the Celtic one.
My suggestion would be to buy a cheap garter somewhere and do something to make it personalized. A lot of the garters on ebay are just a plain garter with some type of charm sewn on. Some of the Disney ones, just have Disney pins attached. Do it yourself!!
