Aesthetic tray design (4)

I believe the answer is:

arty

'aesthetic' is the definition.
(thesaurus)

'tray design' is the wordplay.
'design' indicates an anagram.
'tray' is an anagram of 'ARTY'.

(Other definitions for arty that I've seen before include "Bohemian" , "aspiring to be creative?" , "Culturally creative" , "Having exaggerated air of aesthetic interests" , "Like an aesthete" .)

I've seen this clue in the Evening Standard.
