I am having a co-ed surprise party for my best friend. It is at a local park, where we have rented out a pavilion, there will be a dj, and other fun things. It is in mid-July. I need a theme for everyone to come dressed as, but using just regular everyday clothes, not dress-up. It doesn't have to rhyme or anything, and I'd like it to be sort of fun, maybe even a little bit sexy for the girls. An example of a theme could be wear neon colors. I don't want anything like "dress up as your favorite cartoon character." Thank you so much!
