Delight in predilection to go topless (7)
I believe the answer is:
enchant
'delight' is the definition.
(enchanting is a kind of delighting)
'predilection to go topless' is the wordplay.
'predilection' becomes 'penchant' ('penchant' can be a synonym of 'predilection').
'to go topless' means to remove the first letter.
'penchant' with its first letter removed is 'ENCHANT'.
'in' is the link.
(Other definitions for enchant that I've seen before include "Appeal" , "Delight, cast spell over" , "Entrance" , "Delight, charm" , "transport" .)
