Vintage S Teal Purple Button Front Pleated Madras Plaid Midi Skirt Pastel Spring

Unbranded vintage madras plaid pleated maxi skirt in pastel teal blue and purple. Pearlescent buttons down the front. Tag size 12 but it best fits a modern 12 - please see measurements. The fabric feels like cotton, but because of the pleats I believe there must also be a synthetic fiber woven in as well. Unlined. No stretch. A couple areas of discoloration, please see photos. Smoke and pet free home.
