Hula hoop? (3)
I believe the answer is:
lei
'hula hoop?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lei that I've seen before include "Polynesian garland of flowers" , "Flowers worn round the neck" , "Necklace of tropical flowers" , "Hawaiian necklace of flowers" , "Hawaiian garland of flowers" .)
