Vintage 1960s Floral Maxi Dress XS S Acetate Hippie Bohemian Hippy Flower Power

Amazing vintage 1960s homemade dress! So many colors and a very flattering shape. Zipper closure goes about half way down the back. Mandarin collar. Short sleeves. Maxi length. No tags inside but it feels like acetate and measures like modern day XS-S. Please see pictures for measurements. One flaw near the collar (pictured). Dress is not lined. There is no slit at the bottom. The material does not stretch. The sewing is excellent.
