Dorothy Who? is from the China Glaze - Wizard of Ooh Ahz collection 2009. The original collection was released in 2001 and China Glaze re-released it because fans asked for it. If only they would do that with the OMG collection!
Dorothy Who? is a silver and blue shimmer polish in a dark blue jelly base. This is gorgeous! If you don't already own this one go add it to your wish list now! I'm going to put it on my nails again when I finish this post.
