Scout uniform accessory (4)
I believe the answer is:
sash
'scout uniform 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 "Window frame - shoulder band" , "Sliding window frame" , "Broad band, the one me father wore?" , "Framework holding window panes" , "Ribbon worn over the shoulder" .)
