Vintage Dress Hippy Costume

Vintage, not in perfect shape there are some fries on the sleeves as shown in the photo. I'm not an expert on Vintage but it was sold to me as a piece from the 1960s not sure if it's accurate but it does appear to be 60s or 70s color. It reminds me of irresistible dress JLo wore at the Emmy Awards. Low-cut and form-fitting. There is no size label and it was sold to me as a small but I do find it a little big for my body I'd say more fitting to a small medium please ask for measurements as needed
