Clothing frill (6)
I believe the answer is:
ruffle
'clothing frill' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ruffle that I've seen before include "Disturb the evenness of feelings or feathers" , "Disturb or upset, say feathers" , "Dishevel - annoy" , "Disturb the calm or smoothness of - feathers?" , "Ornamental frill; make disarranged" .)
