The bride will throw the bouquet at all the single women present at the back, and whoever receives the bouquet will be considered as the next person to get married. The groom will take off the bride's garter on the spot (usually to entertain guests) and throw it at all single men. Whoever receives the garter will be considered as the next person to get married. Sometimes garters are sold by lottery, not lost. The man who received the garter should put it on the woman who received the bouquet.
Therefore, the bride will be particularly particular when choosing garters.
It is a tradition to wear garters at European weddings.
