For some reason I notice a lot of box shaped clothing for taller girls. My best friend is 5'9 with a big bust and tiny waist. She goes through so many shops before finding anything.  :( it must be a bitch to find clothing. I like to find dresses and shirts with a pattern that can be resewn and look good, then cut literally inches of cloth from the sides and resew to fit. Not an easy or short task really, but on a college budget, it makes you look and feel AWESOME in your clothes! Good luck~
