you know, anyone can wear whatever they want. but personally i wouldn't go too big on the hoop earrings. but average size ones would look cute.
a lot of people are going with the "babydoll" style tops. i think they're adorable and i wear them all the time. they're flattering, too! a lot of people just wear cute tank tops, cardigans, etc. really there are so many different styles that i can't tell you what kind of tops all girls are wearing... but yes. skinny jeans are in and they're soo cute! try for a colored pair, pastel or bright. pacsun.com has a lot of cute ones!
i noticed that a huge trend around here is gladiator sandals of all types and colors. i personally LOVE them! they're comfortable, adorable, and really stylish. pick out your favorite type. there's a lot to choose from. but if you just want to be casual and simple, go for the class flip-flop. they're perfect.
hope i helped!
