Following cut, one dressed unattractively (5)
I believe the answer is:
frump
'one dressed unattractively' is the definition.
'following cut' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'cut' becomes 'rump' (rump is a kind of cut**).
'f'+'rump'='FRUMP'
(Other definitions for frump that I've seen before include "Dowdy person" , "A dowdily-dressed unattractive woman" , "Dowdily dressed female" , "Jeer" , "Dowdy-clothed woman" .)
