![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
belle
'beauty at a ball' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for belle that I've seen before include "Attractive woman" , "Most attractive girl" , "Beautiful girl" , "Beautiful woman - of the ball?" , "-- Epoque, before the Great War" .)
