100% silk, authentic Prada worn only one time and just dry cleaned! Decent sheen. Really nice baby pink (pic #6 reflects true color best!) Men’s Small = waist 28in (elastic, so could easily go up to 31-32in). Women’s Medium, I’d say. Excellent condition, slight fraying / creases on the triangle on back pocket (pictured). Slight stain on the back right below triangle. Very light silk fabric. Perfect for spring. Measurements listed in pics! -Erich
