For mere pennies, you can have a pretty hanger. This one is for my little girl, but with more mature colors, etc. you could easily make them for adults too. All you need is a basic plastic hanger, yarn of any weight, and something pretty to attach to the neck. I used a wire butterfly from the dollar store. They are sold in packs of 3, so are very inexpensive! A silk flower hot glued to the front would also be cute.
If you'd like a quick and unique baby shower gift, buy a pack of baby hangers and whip up a batch of these for the new little princess. Whatever you do, have fun!
