Daks of London vintage green virgin classic wool skirt suit set

Absolutely amazing green wool skirt suit set. Made in England. Lovingly preserved. I am having a hard time dating this set, and have looked at some textile museum sites. I believe this is from the 1970s, but could be earlier. There’s a small stitch in the back of the skirt (see pic), likely to mend a hole. And there’s some overall wear on account of its age. But this truly is a special set. Both pieces are fully lined. Tagged a vintage size 12. Please check approximate flat measurements to assess best fit for you: Skirt: Across waist approx 14” Length approx 28” Blazer: Pit-pit approx 19” Shoulder-hem approx 24” Sleeve length approx 23”
