Incline to adopt right fashion (5)
I believe the answer is:
trend
'fashion' is the definition.
(thesaurus)
'incline to adopt right' is the wordplay.
'incline' becomes 'tend' ('tend' can be a synonym of 'incline'**).
'to adopt' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'tend' going around 'r' is 'TREND'.
(Other definitions for trend that I've seen before include "Popular current taste" , "The way things are going?" , "Drift; vogue" , "Fashion; general direction" , "Leaning; fashion" .)
