If your single friends are less than excited to be outed or you're a little embarrassed about having your brand-new husband reveal your upper thigh in front of Great Grammy and everyone else, then maybe looking at alternatives to tossing your bouquet and garter are for you.
So many wedding traditions are rooted in superstition but thankfully have evolved into more accepted practices for our culture. For instance, the last I heard, there hasn't been a single sighting of a guest tearing at a bride's dress for good luck! As for the traditional bouquet and garter toss, I've been to weddings where the bouquet was tossed but the garter was not or both traditions were omitted. It's your wedding, what you are comfortable with?
Fun Alternatives:
In lieu of tossing your bouquet to only your single guests~ include everyone in the fun with a "break away" bouquet~ designed to break apart into small bouquets... Or, you can present your bouquet to the longest married couple. Or, give it to an honorary guest like Great Grammy or dear Aunt Betsy. And, in lieu of your new husband removing your garter, why couldn't he just carry a separate garter or any additional fun items and toss those?
Do you think guests look forward to wedding traditions like the bouquet and garter toss and are disappointed when couples decide to forgo them?
