Vintage 70s One of a kind homemade Butterfly Blouse

Based on the inside it's a homemade blouse. Beautiful butterfly print with a large collar and full button-down front. Feels like polyester. This is probably a large. Please see the measurements below. The material is Cal-prints by Stanton-Kutasi and what I found was that they did higher-end Polyester, Silk, Nylon, etc. fabrics. They are still in business today without the Kutasi name. Measurements: PTP 24.5" Length 29" S-S 18"
