Again shattering fashion contrary to natural inclination (7,3,5)
I believe the answer is:
against the grain
'contrary to natural inclination' is the definition.
(I've seen this before)
'again shattering fashion' is the wordplay.
'fashion' indicates anagramming the letters.
'shattering' anagrammed gives 'stthegrain'.
'again'+'stthegrain'='AGAINST THE GRAIN'
(Other definitions for against the grain that I've seen before include "not for a malt whisky drinker" , "Saw deal this way, perhaps" , "contrary to one's inclination?" , "Following the difficult route" , "Joiners sometimes saw this" .)
