Stole from a show?

BOA

This slinky accessory might wrap around your neck but shares its name with a snake that constricts its prey.

This clue plays on the double meaning of "stole." One definition is the past tense of "steal," but it also refers to a long, narrow scarf often made of fur—like a feather boa you might see in a theatrical show. The word "show" hints at performance or fashion, pointing to the accessory rather than the act of theft. So "boa" fits as something you could "steal" from a stage costume.
