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' indicates anagramming the letters (style can mean to shape or design).
'daft' with its last letter removed is 'daf'.
'daf' is an anagram of 'FAD'.
'in' is the 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" .)
