…in close judge robes (6)
I believe the answer is:
trendy
'in' is the definition.
('in' can mean trendy or fashionable)
'close judge robes' is the wordplay.
I cannot really see how this works, but
'close' could be 'end' (I've seen this in another clue) and 'end' is located in the answer.
'judge' could be 'try' (as in trialling a defendant) and 'try' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trendy that I've seen before include "following fashion" , "Less sensible; a dye plant" , "Informally, following the fashions" , "Modish" , "In accordance with the latest fad" .)
