Fashion designer Sui (4)
I believe the answer is:
anna
'fashion designer sui' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anna that I've seen before include "Former Indian coin, girl" , "and eleven, twenty four across heroine" , "-- Karenina, Tolstoy novel" , "- - Kournikova (tennis)" , "Old foreign coin" .)
