More or less following a style (5,1,7)
I believe the answer is:
after a fashion
'more or less' is the definition.
'following a style' is the wordplay.
'following' becomes 'after' (I've seen this in other clues).
'style' becomes 'fashion' (synonyms).
'after'+'a'+'fashion'='AFTER A FASHION'
(Other definitions for after a fashion that I've seen before include "In some manner but not very well" , "To some extent but not perfectly" , "Behind time" , "contrive to be not that well" , "In some (unsatisfactory) manner" .)
