Sweet kiss, warmer? (4,4)
I believe the answer is:
polo neck
'warmer?' is the definition.
(garment which warms the wearer)
'sweet kiss' is the wordplay.
'sweet' becomes 'polo' (I've seen this before).
'kiss' becomes 'neck' (neck can informally mean to kiss).
'polo'+'neck'='POLO-NECK'
(Other definitions for polo neck that I've seen before include "Collar" , "Garment" , "Top" , "Type of jumper" , "clothing item" .)
