Well I did do that robe for the Jane Austen Festival, although it was a bit rushed and needs more work. This isn’t a great photo, but you get the idea:
It’s basically adapted from the Sense & Sensibility pattern, altered to have darts in the front and opens in the front with hooks and eyes. The side and back panels are just rectangles. It has braid along the front and lower edges of the ‘skirt’ . The bodice is a little uneven and needs more decoration, hopefully I’ll do some more work on it in the future.
