Island souvenir (3)
I believe the answer is:
lei
'island souvenir' 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 "change in E. Europe" , "Garland of flowers in Hawaii" , "Polynesian garland of flowers" , "Band of flowers" , "Hawaiian garland of flowers" .)
