Daughter’s after sentimentally pretty fabric (5)
I believe the answer is:
tweed
'fabric' is the definition.
(tweed is a kind of fabric)
'daughter's after sentimentally pretty' is the wordplay.
'daughter' becomes 'd'.
'after' says to put letters next to each other.
'sentimentally pretty' becomes 'twee' (I've seen this before**).
'd' put after 'twee' is 'TWEED'.
(Other definitions for tweed that I've seen before include "Woollen cloth - Scotland/England border river" , "Woollen material" , "Harris cloth" , "Rough woollen cloth" , "Thick woollen cloth - northern river" .)
