Oh man. I used to have a style. I can't really pull it off here in North Carolina though.
Right now I basically wear jeans and band tees with a sweatshirt when needed. And my hat. But I left my hat in Florida, so I need a new one.

In San Diego I would do the jeans and a nice button up long sleeve shirt with the sleeves rolled up to my elbows. Throw in a clean solid black or white pair of shoes and do my hair up a little and I looked goooood.
If I wasn't wearing that I was wearing shorts and a v neck tee with flip flop sandals. Hair again done up a tidbit. I might substitute a rolled up pair of jeans for the shorts sometimes. I liked to turn them into capri-esk pants.
