That sounds really neat! I could never do that, though, lol. However, I do have a LOT of earthtones in my wardrobe, so a lot of my stuff matches, anyway. Other than that, I do have a lot of blacks, greys, navy blue, & a little purple (from the stuff I get on clearance from my school's bookstore, lol.
And...I always have a pair of Converse Chuck Taylors to match ANY outfit
