Rose is the pretty girl in red (8)
I believe the answer is:
rebelled
'rose' is the definition.
('rebel' can be a synonym of 'rise')
'the pretty girl in red' is the wordplay.
'the pretty girl' becomes 'belle' (I've seen this before).
'in' means one lot of letters goes inside another.
'belle' put inside 'red' is 'REBELLED'.
'is' acts as a link.
(Other definitions for rebelled that I've seen before include "Rose in opposition" , "Fought against authority" , "was revolting" , "Revolted" , "Red belle (anag.)" .)
