I own a lot of tops made out of soft, drapey fabric. Since they wrinkle easily, I always put them on a hanger, but the fabric is so slippery that they constantly fall off. On my last visit to Primark I had a little stroke of genius and decided to buy velvet hangers. This way, the slippery fabric stays put and doesn't wrinkle anymore.
The hangers even have a little hook for jewelry!
