They're the best formal hats! (7)
I believe the answer is:
toppers
'hats' is the definition.
(topper is a kind of hat)
I can't explain the rest of the clue.
Can you help me to learn more?
(Another definition for toppers that I've seen is " High hats".)
I've seen this clue in the Sydney Morning Herald.
Want a hint initially instead of a full solution?
