I've never done a fashion show for a school, but waht a great idea for a middle or high school event!
You might try contacting your local mall or even some of the stores in the mall and see if they would be interested in participating(it's sure to bring them some business). Some of them may have some ideas/plans for just such an event.
If you find anything, please post it here, because I'd love to try something at our school too.
Woman Fashion Show
Turn a normal dinner fundraiser into an evening of fun and entertainment. Find some brave men that are willing to embarrass themselves and have a “wo”man fashion show. Get donated dresses or look in local resale shops. You will need wings too, so keep an eye out for these. Find jewelry, shoes and other accessories as well. Set up a dressing room with mirrors for applying make up. Have someone willing to pull up zippers, make sure wigs are on straight, and help apply makeup. Have the fashion show after everyone has been seated for dinner, or during dessert. An emcee should introduce each model. Create a bio for each of them such as, “and next we have Denise, she is six foot five inches tall, and in her spare time she likes to shop for camping gear”. Make it humorous and lighthearted. Everyone is sure to have a good time. You will definitely liven up your next spaghetti dinner.
