How one looks when coming on stage? (10)
I believe the answer is:
appearance
This could be a double definition.
'how one looks' is the first definition.
'appearance' can be an answer for 'looks' (thesaurus). I am not sure about the 'how one' bit.
'coming on stage?' is the second definition.
'appearance' can be an answer for 'coming' (thesaurus). I'm unsure of the 'on stage?' bit.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for appearance that I've seen before include "Semblance" , "it seems" , "Advent" , "Look; impression given" , "Bearing - pretence" .)
