Decades of Fashion
One idea is to have a game where each contestant will have to wear a popular outfit from a certain decade but put her own modern twist on the outfit. For example, one woman may decide to wear vintage bell bottoms with a modern-day graphic T-shirt and boots while another woman may wear a 1920s bob hairstyle with a modern babydoll dress and flip-flops. You'll judge each outfit based on originality the top three winners will get a gift card to a local vintage store.
Restaurant Dress Up Game
If you and your friends eat out often, you can have a game in which everyone has to dress up as food service workers with outlandish work clothes. One guest may decide to wear a roller derby outfit with a bright-colored large chef's hat while another person who wants to portray a waitress may wear a polka-dot dress with a large multi-colored headband and carry a notebook with color pages along with a big vegetable-scented pen to take orders with. You can get a friend or relative to judge each outfit and the winner gets to choose the next party game.
Politician Impersonations
If you and your friends keep up with current events, you can have a game where the guests will dress up as popular female politicians such as Nancy Pelosi, Sarah Palin or Hillary Clinton. In addition to the outfits, you can conduct a mock televised campaign debate where you'll ask each person three questions about issues such as immigration, foreign policy and the economy. The winners with the best impersonation will get a bag of political magazines and a political poster.
