Gorgeous Vintage Mexican Embroidered Dress no size

Beautiful Mexican embroidered sack dress. There is no size label so it is likely handmade. The fabric of the dress feels like a polyester, while the panel that the flowers are on, feels more like a cotton. The lace around the collar and sleeves and bottom of the dress looks to be hand tatted. There are a few pulled threads, so good used vintage condition. Approximately 21 inches pit to pit!
