Endless daft style in vogue (3)
I believe the answer is:
fad
'vogue' is the definition.
(fad is a kind of vogue)
'endless daft style' is the wordplay.
'endless' means to remove the last letter.
'style' is an anagram indicator (style can mean to shape or design).
'daft' with its last letter taken off is 'daf'.
'daf' with letters rearranged gives 'FAD'.
'in' acts as a link.
(Other definitions for fad that I've seen before include "A craze, usually passing" , "A passing fashion or craze" , "A craze or current vogue" , "Personal whim" , "transient success" .)
