In all the years I've been selling vintage clothing, I have only had three dresses from the 1920's with labels in them, and two of those dresses just went up for sale today in my EBay store . The first is a stunning beaded dress dating to about 1921 by Lucy Perret, Paris. I can't find any information about Miss Lucy anywhere, but I would imagine she was a small custom dressmaker, as the dress is completely sewn by hand and has exquisite detailing.
The second is another outstanding beaded dress by Adair, Paris dating to about 1924. The House of Adair made beaded dresses in France for export to the Unites States, United Kingdom and Canada. This dress is also completely sewn by hand.
Finally today, we have a gorgeous 1920's black silk and ermine fur coat with a label from Porteous, Mitchell, and Braun, the finest department store in downtown Portland, Maine.
