A Victorian Lady’s finishing touch—the chatelaine. (From Wikipedia)

A chatelaine is a decorative belt hook or clasp worn at the waist with a series of chains suspended from it. Each chain is mounted with a useful household appendage such as scissors, thimble, watch, key, vinaigrette, household seal, etc.
Chatelaines were worn by many housekeepers in the 19th century and in the 16th century Dutch Republic,where they were typically used as watch chains for the most wealthy. Similar jewellery was also worn by Anglo Saxon women, as seen from the burial record, but its function is uncertain. The name chatelaine derives from the French term châtelaine
