Cavalier poet's fondness for fine fabric (8)
I believe the answer is:
lovelace
'cavalier poet's' is the definition.
(I've seen this in another clue)
'fondness for fine fabric' is the wordplay.
'fondness' becomes 'love' (I've seen this before).
'for' says to put letters next to each other.
'fine fabric' becomes 'lace' (I've seen this in another clue).
'love'+'lace'='LOVELACE'
(Other definitions for lovelace that I've seen before include "Cavalier poet" , "Poet's daughter" .)
