I bought an Edwardian bodice and replicated it for my daughter. With a simple skirt and some accessories she now has a full outfit.
I turned a pair of thrifted silk curtains into a Victorian silk petticoat. I also dyed my cotton lace to match using common food items.
I am building my Regency/Empire outfit. Now I have finished my stays, a bodiced petticoat and a bonnet. Only my gown is still missing.
