'clothing' is the definition.
(mufti is a kind of clothing)

I don't understand the rest of the clue.

(Other definitions for mufti that I've seen before include "Soldier's civilian clothes" , "Civilian dress, in army terms" , "Civilian clothes worn by service personnel" , "Non-military clothing" , "Civilian clothing; Muslim legal expert" .)

I've seen this clue in The Times.
