We did the garter toss too, and Hubby certainly didn’t pull it off with his teeth! I wore mine below my knee too and he removed it modestly. It was absolutely adorable - my brother’s then-fiancee (now his wife of several years) caught the bouquet, and my brother was going for the garter when he was caught out by my little cousin who was then 6 years old! My garter had a blue ribbon in it because that was my “something blue”. (Something old - my shoes, a nice second-hand pair from my mom; something new - my wedding dress; something borrowed - my mother’s pearls which I gave back to her afterward; something blue - my garter.)
The garter toss stemmed from a time back in the day when it was important that the marriage be consummated immediately. The custom was that the guests would follow the couple back to the bedroom and the couple would go in and shut the door. The groom would later reappear with a piece of the bridge’s underclothing as evidence that the marriage had been consummated. A garter was considered a piece of intimate apparel at the time, so it was often the piece of underclothing that the groom brought out. Later, this was adapted into the garter toss.
