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. They were very popular from the 1860's until the end of the century.
