Formal accessory page Henry wears fitting perfectly (3,3)
I believe the answer is:
top hat
'formal accessory' is the definition.
'top hat' can be an answer for 'accessory' (type of hat). I am unsure of the 'formal' bit.
'page henry wears fitting perfectly' is the wordplay.
I cannot quite understand how this works, but
'page' could be 'p' and 'p' is found within the answer.
'henry' could be 'h' (symbol for the unit of electrical inductance) and 'h' is located in the answer.
'perfectly' could be 'toat' ('to a T' or 'to a tee' can mean perfectly) and 'toat' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for top hat that I've seen before include "It is worn with tails" , "It's seen with tails" , "Fancy lid" , "Film with Astaire and Rogers" , "1935 Astaire/Rogers film" .)
