Die in attempt to be fashionable (6)
I believe the answer is:
trendy
'be fashionable' is the definition.
(similar in meaning)
'die in attempt' is the wordplay.
'die' becomes 'end' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'attempt' becomes 'try' (synonyms).
'end' going inside 'try' is 'TRENDY'.
'to' acts as a link.
(Other definitions for trendy that I've seen before include "Fashionable, in style" , "Cool" , "Voguish" , "Informally, following the fashions" , "With it, a la mode" .)
