Feature of a witch costume (4)

I believe the answer is:

wart

(Other definitions for wart that I've seen before include "Horny skin growth" , "Small hard excrescence on the skin" , "Small hard growth on skin caused by virus" , "skin problem" , "Disfiguring growth on skin" .)

I've seen this clue in The New York Times.
