Correct girl coming out, huge when undressed (5)
I believe the answer is:
debug
'correct' is the definition.
(debugging is a kind of correcting)
'girl coming out huge when undressed' is the wordplay.
'girl coming out' becomes 'deb' (short for debutante).
'when undressed' says to take the centre.
The centre of 'huge' is 'ug'.
'deb'+'ug'='DEBUG'
(Other definitions for debug that I've seen before include "Remove (software) errors" , "Remove errors from (programme)" , "Fix software glitches" , "Remove problem" , "Remove errors from a computer program" .)
