I generally care more about the cut and design of a dress, or I choose not to buy an item because of a certain pattern, but I guess I could narrow it down to a couple of favorites.
First and foremost would be Chocolate prints. It is no secret that I am dying to get my hands on a good chocolate print, but nothing yet. None of the cheep looking, super sweet ones though.
A close second would be books/library prints. Some of them can be obnoxious and far too busy, but a few of them are really elegant and well designed.
