Woman’s bathroom clothes — one maiden’s legacy (8)
I believe the answer is:
heirloom
'legacy' is the definition.
(heirloom is a kind of legacy)
'woman's bathroom clothes one maiden's' is the wordplay.
'woman's' becomes 'her' (belonging to a woman).
'bathroom' becomes 'loo' (loo is a kind of bathroom).
'clothes' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'maiden' becomes 'm' (cricket abbreviation).
'her'+'loo'='herloo'
'herloo' enclosing 'i' is 'heirloo'.
'heirloo'+'m'='HEIRLOOM'
(Other definitions for heirloom that I've seen before include "Valuable object handed down" , "Valuable family object" , "Family bequest" , "Hand-me-down" , "Cherished item passed down through generations" .)
