Rich or costly, like velvet (5)
I believe the answer is:
plush
I believe this is a triple definition!
'rich' is the first definition.
(similar in meaning)
'or' acts as a link.
'costly' is the second definition.
(thesaurus)
'like' is a link.
'velvet' is the third definition.
(I know that plush is a type of velvet)
(Other definitions for plush that I've seen before include "Fabric; richly luxurious" , "Fabric with a long velvety pile" , "Cut pile, softer than velvet" , "Rich fabric" .)
