You can have this and still be clothes-mad! (5,5)
I believe the answer is:
dress sense
'you can have this and still' is the definition.
I know nothing about this answer so I can't judge whether this works.
'be clothes-mad' is the wordplay.
'be clothes' becomes 'dress' (I've seen this before).
'mad' becomes 'sense' (I am not sure about this - if you are sure you should believe this answer much more).
'dress'+'sense'='DRESS SENSE'
Can you help me to learn more?
(Other definitions for dress sense that I've seen before include "Good instinct for selecting garments" , "style" , "Good taste in clothes" , "What fashion icons have" , "Instinct for clothes" .)
