Shopping

UrbanOutfitters - They have some pretty wild shoes, some killer printed tees, and trendy apartment stuff
American Eagle - I am absolutely in love with this store
JCrew - When I graduate, I am going to buy a really cool tailored suit from here, but for now I'll stick with bathing suits and tshirts
Old Navy - you know you love it
Free People - owned by Urban Outfitters; a little pricier and you can't shop online, but it's fun to look at the pictures
Anthropologie - also owned by Urban Outfitters; more of a dressy place, also kind of expensive, but all their stuff is gorgeous!
