Looking embarrassed (3-5)
I believe the answer is:
red-faced
'looking embarrassed' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for red-faced that I've seen before include "Rubicund" , "Visibly ashamed" , "Embarrassed-looking" , "Having glowing visage, embarrassed" , "Colourfully embarrassed" .)
