i just moved to austin recently from new york, by george is the only boutique that rivals my selections in new york
they have two stores. one is on lamar@6th street and is more designer focused with lines like marni, lanvin, bottega veneta, proenza schouler, & more & more & more. the congress location is more young contemporary and has see by chloe, paul & joe, j brand, madison marcus, shipley & halmos, etc. both locations have a lot of new or hard to find designers including local artisans & a few organic lines like loomstate & beau soleil.
i always manage to find a gazzilion things i like there and the girls are always so enthusiastic and professional. i recommend any austinite or austin visitor stop by the best boutique in the lone star state!!!
