One of our favorite things..divide the guest into two teams, more if you have a lot of guests. Give each team plenty of toilet paper and ask them to create the bride's wedding gown. The bride does not play, she chooses the winner. One person on each team is the model that is adorned with all the TP. It is a lot of fun.
Another..this is a great break the ice game. Ask each guest to bring what they wear to bed in a brown paper bag. All bags are gathered as guests arrive so no one really knows who brought what. The hostess goes bag by bag and each guest tries to guess who's pj's belong to who. We have seen everything from empty, whip cream, chocolate, sexy lingerie and flannels..lol. Lot's of fun.
Another thing we do. Give each guest a clothes pin as they enter the shower. When all guests arrive and the shower has officially started..explain to the guests that they can not cross their legs. Each time a guest is caught by another guest crossing their legs, the guest that catches the leg crosser takes the crossers clothes pin away from them. At the end of the shower the guest with most clothes pins gets a prize, if you chose to do prizes.
Also..we mark one (sometimes two if the shower has a lot of guests) the bottom of the paper plates used for dinner/cake and whoever gets the plates marked with X on bottom wins a prize.
Another thing. You could make a list of 10 questions or so, all relating to bride. Shortly before you start this game, ask bride to leave the room discreetly. Start the game, ask the questions, then ask bride to come back in room for answer part. The guest with most correct answers wins a prize.
What color shirt/blouse. How many rings is she wearing, etc.
