Luau necklace (3)
I believe the answer is:
lei
'luau necklace' 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 "Flowers worn round the neck" , "Blooming string" , "Hawaiian flower garland" , "Floral decoration" , "Bloomers on line" .)
