Looking at female quality in jacket for evening (5)
I believe the answer is:
eying
'looking at' is the definition.
(I've seen this before)
'female quality in jacket for evening' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eying that I've seen before include "Looking at closely" , "Ogling," , "In the process of close scrutiny" , "Fixated on" , "Interested in visual appearance" .)
