Vintage 70s Mexican pattern maxi dress

This dress is a knocker! The dress is maxi length but the waist is high waisted that has a stretch, it will make you look slimmer. It has kimono sleeves and zipper in the back for easy wear and off. It is mock neck. It has a ribbon and tiny opening in the back. Material feels like very thin polyester. The front has little bit of thread came off but you can easily sew it. I kept the dress very carefully and well, but I don’t know where this stain came from, it has a sticky brown stain on the bottom of the dress. You can wash this dress in the dryer and remove it, but due to age of this dress, I recommend dry cleaning. Measurements are 17.5” shoulder width, 12” from the top of the dress to the waistline, 18” waist width when not stretched, 20.5” when stretched 56.5” total length, because it’s a drop shoulder and has no cut, I cannot measure the sleeve length. The opening in the back with a ribbon. Other than the thread coming loose and the stain, In excellent condition. No flaws. Comes from pet friendly and smoker home.
