Closet Purge

Hello friends! So I'm in Idaho and it's heating up astonishingly fast here. Ive decided to purge my closest of anything I haven't worn in the last year and find things that are more 'me'. I'm going Bohemian this summer! Also I'm going to Europe for a couple weeks and I would like it if I could look somewhat cute. Does anyone know of a place I could get the flowy dresses, cute skirts? bell-bottom pants and short denim skirts should be a must. :) And I'm obsessed with those wide brim hats. I'd like a place that doesn't break the bank since I'd still like to eat and whatnot. Thanks!
