One of my favourite vintage shops, specialising in 60s and 70s designer clothing, has this gorgeous black dress from Carven Paris for Marcel Fenez in at the moment.
The dress is princess line with spaghetti straps and a full skirt. It’s made from faille, so the skirt hangs in a beautiful structural style, and it has fabulous fringing around the top of the bodice.
I would say the size looks around a modern 12-14 from the measurements, so not super tiny either. A good party season investment!
