Mexico City Brand Cotton Gauze Dress or Jacket NWOT

I purchased this garment in Mexico City. It doesn’t have a size or care tag. I think it’s a woven cotton or linen blend. Very nice, drapey, gauze fabric. Can be used as a jacket, dress, or bathing suit cover-up. Very versatile. I never ended up wearing it so it’s brand new. Length is 44” Shoulder to shoulder measurement is 18” Fit is S to M
