jacket: zara (similar)
polka dot pants: j.crew factory (exactly)
boots: stuart weitzman
bag: phillip lim for target
creative: pattern mixing! stripes and snakeskin-ish print together!
young: the combination of a big top and skinny pants has a tendency to seem very young/casual to me, but simple boots and a structured jacket help lessen that.
professional: jacket layer, black boots, and a black bag. you know, the usual 'round here.
