Meeting to design coats (5)
I believe the answer is:
ascot
'meeting' is the definition.
(horse racing meeting)
'design coats' is the wordplay.
'design' is an anagram indicator.
'coats' with letters rearranged gives 'ASCOT'.
'to' is the link.
(Other definitions for ascot that I've seen before include "Royal Berkshire race-meeting (and fashion show!)" , "Racecourse near Windsor" , "Necktie with wide square ends" , "English racecourse in Berkshire" , "Town with racecourse" .)
