One with a suit: a male with more awful clothing (7)
I believe the answer is:
admirer
'one with a suit' is the definition.
(suit can mean an attempt to woo - as in a suitor)
'a male with more awful clothing' is the wordplay.
'male with' becomes 'm' (I am not sure about this - if you are sure you should believe this answer much more).
'more awful' becomes 'direr' ('dire' can be a synonym of 'awful').
'clothing' means one lot of letters goes inside another (some letters cover up or clothe others).
'm' going within 'direr' is 'dmirer'.
'a'+'dmirer'='ADMIRER'
(Other definitions for admirer that I've seen before include "One who regards (someone) with respect" , "Supporter or fan" , "Hopeful lover?" , "A young lady's beau - he thinks she's great" , "potential suitor" .)
