Finding Cinderella

Men have to find out the woman whom the footwear fits and ask for a dance. 

Even when everyone is witnessing the bouquet or garter throw, ask all the single boys to gather to one side and make them stand in a row along the length of the room while looking the other side and keep women in the middle. 

Turn to the women and ask them to leave one of their footwear in the middle of the dance floor.  Now request them to return to their spot while concealing the other pair behind.   

Ask the men to turn around, get hold of footwear and try finding the person who was wearing it.  The footwear they have in hand will choose their dance partner for a song.  Be watchful of the ladies, lest they may try to help the mistaken guy by saying the footwear is not theirs without putting it on.

Once the guys have met the ladies fitting the footwear, play songs, and let them take pleasure of dancing with their new partner. You have succeeded in bringing all singles on the floor early on.
