Pseudocultural (4)
I believe the answer is:
arty
'pseudocultural' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arty that I've seen before include "Trendily into painting" , "Affectedly unconventional" , "Pretentiously cultural" , "Making a point of appearing interested in painting, sculpture etc" , "aspiring to be creative?" .)
