Something to do for dinner? (5)
I believe the answer is:
dress
'do for dinner?' is the definition.
'dress' can be an answer for 'do' (synonyms). I'm unsure of the 'for dinner?' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for dress that I've seen before include "Garb" , "Costume" , "formal attire" , "items to wear" , "Clothing - groom" .)
