I inherited a two piece midnight blue velveteen dress that originally belonged to a great-great aunt, who lived in Maine and Boston,MA from 1844-1917. I would love to have an approximate date of this dress. I want to donate this to a local historical society and any info would be very helpful. Jacket has a decorative braided trim and it is lined with an soft ivory satiny finish material. Both skirt and jacket have hook and eye closures. Looks to be designed to wear with a corset. No label. Thanks for any info you may provide.
