I'm 25, but I guess I'll answer.
Shorts and a tank top can be really attractive. Tight jeans are okay, I find a nice skirt much more attractive though, that and skirts with thigh high socks is just a godly combination. A nice sundress can be extremely cute, that's one of my favorites.
Overall it's going to be more about your style than anything else. If you fit a style I like, I'm probably going to find it attractive.
