Designer Saint Laurent (4)
I believe the answer is:
yves
'designer saint laurent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yves that I've seen before include "French man" , "Montand, Fr. actor" , "-- Saint-Laurent, French fashion designer" , "-- Saint-Laurent, couturier" , "__ Saint Laurent, couturier, d. 2008" .)
