Can anyone think of some meaningful replacements or substitutes for the garter at a wedding reception?

My bride is very reserved and we aren't going to follow such a revealing tradition. I can imagine how embarring it will be for me to be lifting her dress in a crowd of people. We've had several suggestions from coworkers and family, but haven't found one that would suit us. She is still tossing a bouquet, and we want to find something comparable, or meaningful that the groom (me) can throw. These could be things that I could take off of her, or from her. Of course, these are also things which might bring luck to the single guy who catches it. Suggestions so far: my little black book (past girlfriends #'s, which I don't have), lady's handkerchief, baseball glove (?), her bracelet, her tiara, etc. Any ideas will be more than appreciated.
