I don't know my only style of clothing?

My mom keeps complaining that I'M 2 hard 2 shop 4. I don't know what 2 tell her, bcuz I don't know specifically what I like... I wear a lot of sports clothing... i wear a lot of rainbow color bright clothing... I also wear a lot of preppy A.E. and Hollister clothing. My birthdays coming up... and the only thing I can tell her 2 get me is a pair of Aqua converse... or a pair of white and blue Puma's. I can't decide which style I am... so I have tons of clothing. 4 different outfits... HELP PLZ!!?
