Daughter put on a cloak showing patterned cloth (6)
I believe the answer is:
damask
'patterned cloth' is the definition.
(I've seen this before)
'daughter put on a cloak' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'put on' is a charade indicator (letters next to each other).
'cloak' becomes 'mask' (synonyms).
'd'+'a'+'mask'='DAMASK'
'showing' is the link.
(Other definitions for damask that I've seen before include "Heavy embroidered linen" , "Fabric used for table linen" , "Reversible fabric - type of rose" , "Cloth, originally Syrian" , "Lustrous cloth" .)
