More or less following a trend (5,1,7)
I believe the answer is:
after a fashion
I believe this clue is a double definition.
'more or less' is the first definition.
'following a trend' is the second definition.
(I've seen this before)
(Other definitions for after a fashion that I've seen before include "To a certain extent" , "Following a fad" , "contrive to be not that well" , "Not completely" , "Following a trend" .)
