Advice about senior prom for a clueless tomboy living under a rock? Please and Thank you!?

get a dress you can get cheap ones at clearance sections like macys and jcpenny or look at other stores they have cheap and cute ones at lots of stores that arent clearance like bonton has a lot of really cute ones or u can look at a thrift store or ask ur school if they have places where u can get a discounted or free dress so just look around ask around and have fun :)
