Order in mink dress with order for robe (6)
I believe the answer is:
kimono
'robe' is the definition.
(kimono is a kind of robe)
'order in mink dress with order' is the wordplay.
'order' becomes 'o' (abbreviation e.g. in British honours OM, OBE etc.).
'in' means one lot of letters goes inside another.
'dress with' is an anagram indicator (I've seen 'dressed' mean this ('dress' can mean 'prepare')).
'order' becomes 'o' (abbreviation e.g. in British honours OM, OBE etc.).
'mink' with its letters mixed up with 'o' can make 'kimno'.
'o' placed inside 'kimno' is 'KIMONO'.
'for' acts as a link.
(Other definitions for kimono that I've seen before include "Japanese dress" , "Japanese style of robe or gown" , "Long loose Japanese robe" , "Traditional robe in Japan" , "Traditional Japanese robe with wide sleeves" .)
