Musician finds setter wearing kinky boots (6)
I believe the answer is:
oboist
'musician' is the definition.
(oboist is a kind of musician)
'setter wearing kinky boots' is the wordplay.
'setter' becomes 'i' (the person that set the crossword).
'wearing' means one lot of letters goes inside another.
'kinky' is an anagram indicator.
'boots' anagrammed gives 'obost'.
'i' going within 'obost' is 'OBOIST'.
'finds' is the link.
(Other definitions for oboist that I've seen before include "Instrumentalist" , "orchestra member" , "Player of woodwind instrument of treble pitch" , "Wind player" , "Musician who plays woodwind of treble pitch" .)
