Kiss and draw formal attire (7)
I believe the answer is:
necktie
'attire' is the definition.
(I know that necktie is a type of neckwear)
'kiss and draw' is the wordplay.
'kiss' becomes 'neck' (neck can informally mean to kiss).
'and' says to put letters next to each other.
'draw' becomes 'tie' (synonyms).
'neck'+'tie'='NECKTIE'
'formal' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for necktie that I've seen before include "Item of (American) clothing" , "Long narrow piece of material worn knotted at the front" , "Band in the US" , "Male dress item (US)" , "Garment typically for a man" .)
