blue button up blouse

i love my blue button up so much that i chose to wear it for my first day of school (which might i add was not so great; after going to the university of san francisco, pierce college is really crappy - crappy teachers, crappy campus, crappy classmates). here's 2 other girls who love their blue button ups & wear it the same way i do - with the sleeves rolled up & a little loose:

(sea of shoes)

(madison mag)

for a good blue button up i'd recommend american apparel's pinpoint oxford button up. i'm thinking about maybe buying it in gray.
