An interesting paragraph notes the change in dress style accompanying the influx of women designers.
A couple of other things influenced the movement in England and carried over here. One was the Rational Dress Society. Prior to the Arts and Crafts movement, women had to wear corsets and stays, which were tight around the waist and the neck. Arts and Crafts movement artists opted for very soft, flowing clothing—art clothing—which mainstream women didn’t wear.
This tallies with a photograph of Dorrie taken at Crafnant with her husband which shows a very much loose dress in the arts and crafts style.
