Beauty pageant accessory (4)
I believe the answer is:
sash
'beauty pageant accessory' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sash that I've seen before include "seen hanging around Miss World?" , "Broad band, the one me father wore?" , "Window frame; silk band" , "type of cord?" , "Style of window" .)
