Fashion designer Perry (5)
I believe the answer is:
ellis
'fashion designer perry' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ellis that I've seen before include "Havelock --, psychologist" , "- - Peters (Cadfael writer)" , "who wrote sexy books?" , "-- Island, New York entry point" , "- - Peters (novelist)" .)
