I just ran across this collection of mix and match outfits on the Banana Republic site (via a collaboration with Lucky Magazine) and thought it was a great representation of how far a capsule wardrobe can take you if you pick a single color palette that looks good on you.
Obviously, not all the pieces have to come from BR but they illustrate the point nicely. Plus, everything here could fit in a suitcase if you're traveling for work. Oh, the possibilities!
Check out the items here.
I hope everyone has a happy weekend! Think of me while you're out shopping and I'm stuck at home doing manual labor... :-/
