Do you like bachelor games? If yes, then this one will certainly amuse you. Conduct a bachelorette party and ask all the guests to bring lingerie as a token of appreciation or gift. Make sure that all are not the same types. Let the beautiful bride guess that who gave her what! when she unwraps them.
You can also pitch in a certain amount to gift her a beautiful set of underwear that she probably wouldn't splurge on herself. Let just say from Victoria's Secret or Agent Provocateur.
