New fashion, the latest from our collection (6)
I believe the answer is:
modern
'new' is the definition.
(I've seen this before)
'fashion the latest from our collection' is the wordplay.
'fashion' becomes 'mode' ('mode' can be a synonym of 'fashion').
'the latest from' suggests the final letters.
The last letters of 'our collection' are 'rn'.
'mode'+'rn'='MODERN'
(Other definitions for modern that I've seen before include "Novel" , "Up to date, of present times" , "'Contemporary, up-to-date (6)'" , "Belonging to the present or recent times" , "Activity of 18 ac" .)
