I’ve owned this for some years and love it, but have never quite been able to work it out date wise! I shall leave it for someone else to work out - some real Arts and Crafts details, but also has a traditional folk clothing look. I’d say it’s 1970s at latest, but could be earlier.

I think I wore it on a handful of occasions as a duster coat over jumpers, as it’s a good layering item. Three button fastening with loops, and kimono cut means it’s fairly free sized. 

Condition: 

Some age/very old storage lines to centre of sleeves and corner of bottom hem, have carefully handwashed cool a few times and did improve gradually - may continue to lift. Always too scared to do anything aggressive to it cleaning wise! I happily wore as is, it’s not glaringly obvious. 

Missing blanket stitch at sleeve hems and around neckline, but majority intact. Please see photos.
