Have you checked out Target's adorable pop-up store on Michigan Avenue? The space, which occupies two stories in the Tribune Tower building, is only open for three short days.
I went there--ostensibly for work--and ended up trying on a bunch of clothes and buying a Tracy Feith for Target swim cover-up/tunic. While in the dressing room, I eavesdropped on the resident fabulous gay guy as he dispensed fashion advice to the masses (and the videographer following him around): "Oh my gawd, I'm just loving white on white this season, don't you?...Pair this with a little cuffed jean, maybe a skinny leg?"
The whole shop has the vibe of hipster farmer's market/arty bazaar, and it does a great job of showcasing Target's many exclusive product lines, not just fashion labels, but brands like Smith & Hawken, @Home, Up and Up, DwellStudio, Liz Lange Maternity, Pixi by Petra, Umberto, Converse One Star and Archer Farms.
