How many of the costumes were “made from scratch” and what percentage are vintage?

I cannot say the exact percentage, but where possible I used vintage clothes. In other cases, I used pieces of authentic embroidery, lace, or buttons that I found in the London vintage market, applying them on corsets or dresses made with new fabric. I also used vintage men’s jackets, waistcoats, scarves, and hats when the actors measurements and characters would permit.
