More close-fitting silken pants I must wear with Romeo (8)

'more close-fitting' is the definition.
Both the answer and definition are comparative adjectives.
Perhaps you can see a link between them that I can't see?

'silken pants i must wear with romeo' is the wordplay.
'pants' indicates anagramming the letters (UK informal term for 'nonsense' or 'rubbish').
