Sumptuous and high-end... (5)
I believe the answer is:
plush
'sumptuous' is the definition.
(I've seen this in another clue)
'and high-end' is the wordplay.
'and' becomes 'plus'.
'end' indicates one should take the final letters.
The last letter of 'high' is 'h'.
'plus'+'h'='PLUSH'
(Other definitions for plush that I've seen before include "Fabric; richly luxurious" , "Cut pile, softer than velvet" , "Fabric with a long velvety pile" , "Rich fabric" .)
