Rather posh maker put into disarray (2-6)
I believe the answer is:
up-market
'rather posh' is the definition.
I can't judge whether this definition defines the answer.
'maker put into disarray' is the wordplay.
'into disarray' indicates anagramming the letters (letters scattered around).
'maker'+'put'='makerput'
'makerput' anagrammed gives 'UP-MARKET'.
Can you help me to learn more?
(Other definitions for up-market that I've seen before include "Of high cost and quality" , "Sold to more affluent clientele" , "Relatively superior and/or expensive" , "Relating to the affluent sector of the economy" , "Relating to superior commercial products" .)
