"Fantasy Island” prop (3)
I believe the answer is:
lei
'fantasy island prop' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lei that I've seen before include "Hawaiian necklace of flowers" , "Garland of flowers, may accompany 5 Down" , "Flower garland of Hawaii" , "Hawaiian ring of flowers" , "Blooming string" .)
