Make better clothes available in Dior's business? (7)
I believe the answer is:
couture
'business?' is the definition.
(couture is a kind of business)
'make better clothes available' is the wordplay.
'make better' becomes 'cure' (I've seen this before).
'clothes' is an insertion indicator.
'available' becomes 'out' (I've seen this in other clues).
'cure' enclosing 'out' is 'COUTURE'.
'in dior's' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for couture that I've seen before include "High fashion design" , "High-fashion dressmaking" , "Dress designing" , "Design and manufacture of clothing" .)
