Fashionable, some kitsch, I confess (4)
I believe the answer is:
chic
'fashionable' is the definition.
(chic means stylish or fashionable)
'some kitsch i confess' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'CHIC' can be found hidden inside 'kitsch i confess'.
(Other definitions for chic that I've seen before include "Fashionably smart" , "Unwanted sounds" , "Elegantly stylish" , "French elegance" , "Modish" .)
