Pretentiously artistic outfits for church (6)
I believe the answer is:
kitsch
'pretentiously artistic' is the definition.
I can't judge whether this definition defines the answer.
'outfits for church' is the wordplay.
'outfits' becomes 'kits' ('kit' can be a synonym of 'outfit').
'for' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'kits'+'ch'='KITSCH'
Can you help me to learn more?
(Other definitions for kitsch that I've seen before include "Garish or vulgar items" , "Item of pretentious bad taste" , "Excessively garish or sentimental" , "Sentimental, tasteless stuff" , "Tawdry art" .)
