Rita and Ted, fashionably dressed (7)
I believe the answer is:
attired
'dressed' is the definition.
(attiring is a kind of dressing)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for attired that I've seen before include "surrounded by duds" , "got up" , "Wearing clothes" , "Dressed or clothed" , "Turned out" .)
