Vintage C&A Western Corduroy Shirt Dress Size XS

Contrasting floral and plaid panels. Half button down. Unlined. Belt loops yet missing belt. I believe this is from the 1970's. No size tag, yet the best guess is XS. Approximate flat measurements: 14.25" bust, 13" defined waist, 32.5" length. In good used vintage condition - missing belt, some loose threads, one discoloration spot (most likely will come out when laundered)
