Prepare clothes (5)
I believe the answer is:
dress
I believe this is a double definition.
'prepare' is the first definition.
(I know that dress is a more specific form of prepare)
'clothes' is the second definition.
(dress is a kind of clothes)
(Other definitions for dress that I've seen before include "female garment" , "habit" , "Something made from fabric" , "Costume" , "One-piece garment" .)
