Top + skirt: Texas Trash (Mod faves online: this, this or this). Bag: JCrew. Hat: H&M (similar). Shades: Ray Ban. Shoes: Valentino (these or these work – the latter are gorge in real life)
I found this warm two piece while in Texas and was on that border of I hate it/no I love it which sort of made me want it more. Anything Mad Men-ish gets my attention. Wore it with Valentino flats but square toed flats or sling backs would work just as well.
My other fave retro look is here. Definitely wearing that again with kitten heels.
