Might get itch in long dress (8)
I believe the answer is:
clothing
'dress' is the definition.
(I know that dress can be written as clothing)
'might get itch in long' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
'long' could be 'l' and 'l' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for clothing that I've seen before include "Possibly drag" , "Apparel, garb" , "trousers?" , "See 8" , "Wear" .)
