Holiday skin don't unequip

Pls help me unequip

When you click on the vanity item category in the bottom left (i.e. Back, Shoulders, Head, etc.) the inventory slots in the middle of the screen should show all the vanity items you own. Click on the one you’re wearing. A button should pop up in the bottom right of the screen, “Unequip.”

Contact support, I’m sure someone will try to help as soon as possible
