Tailor item in sale acquired by nouveau riche (8)
I believe the answer is:
Here is my best explanation:
'tailor' is the definition.
(I've seen this before)
'item in sale acquired by nouveau riche' is the wordplay.
I cannot quite see how this works, but
'item' could be 'lot' (I've seen this before) and 'lot' is found within the answer.
an anagram of 'riche' is 'chier' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
(Other definitions for clothier that I've seen before include "Merchant who sells men's suits etc", "One selling material or garments", "tailor", "Seller of garments", "Shopkeeper", "who has particular habits?", "Draper", "Person who sells garments", "Supplier of things to wear" and "Outfitter".)
