Fashion supplier, one not so clever yesterday in Paris (8)
I believe the answer is:
clothier
'fashion supplier' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'one not so clever yesterday in paris' is the wordplay.
'one not so clever' becomes 'clot' (I can't explain this - if you can you should believe this answer much more).
'yesterday in paris' becomes 'hier' (I've seen this in another clue).
'clot'+'hier'='CLOTHIER'
Can you help me to learn more?
(Other definitions for clothier that I've seen before include "Supplier of things to wear" , "Garment maker or seller" , "Seller of garments" , "Shopkeeper" , "Draper" .)
