You should try going for the 1950's pin up look. That's what I would go for in an attempt to stand out from all the poodle skirts that will be there. Hair tutorials: Outfit ideas:
Wear fitted denim capris, a white button front shirt folded under and tied in front so it's like a fitted crop top. Then wear a one strand choker pearl necklace, your hair in a high ponytail witha small silk scarf tied around it, and reddish lipstick. For shoes, wear flats. You'll have an easy and totally authentic rock n' roll 50's look!! : }
1950's, you would want a poodle skirt with saddle shoes and a short sleeved top. If that's too much, then some jeans rolled up at the bottom with a white t-shirt and a pair of converse tennis shoes.
