Strip for a pageant (4)
I believe the answer is:
sash
'strip for a pageant' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sash that I've seen before include "Baldrick" , "Band of cloth" , "(Uniform) strip; window-frame" , "Framework holding window panes" , "Popular band in Northern Ireland" .)
