Warehouse party requiring formal dress to be worn (6)
I believe the answer is:
godown
'warehouse' is the definition.
(I know that godown is a type of warehouse)
'party requiring formal dress to be worn' is the wordplay.
I cannot quite understand how this works, but
'party' could be 'do' (do is a kind of party) and 'do' is found in the answer.
'dress' could be 'gown' (gowning is a kind of dressing) and 'gown' 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 godown that I've seen before include "eastern warehouse" , "Leave university" , "storage facility in India" .)
