Kelly (appropriately named Flickr member RedOrangePink) arranged her closet by color, complete with cute color-matched hangers; perhaps this is not by itself such an unusual closet strategy, but we think the reason it really works in this bedroom has to do with the rest of the room's décor.
By embracing bright color with her bedding, flooring, and lighting (that great pink lamp!), Kelly makes the display of her clothes seem like a natural extension of her decoration scheme. Of course, it helps that the "closet" is orderly as well. We also love the choice of the black and white artwork with just a hint of color, leaning up next to the mirror; it provides the perfect subdued contrast to the rest of the room.
