balenciaga sleeveless color silk block dress

I bought it from TJMAXX in2016size 2, side zipper(27cm), asymmetric V neck, details near the shoulder ( front and back), no other content labels. Shoulder to hem; 86cm Breast: 84cm Waist: about 84cm Worn once, too big for me. Some wrinkles, and there is a pin hole near the label. No other imperfections or signs of worn. It was with the paper Balenciaga label pouch, I am still trying to find it. As I remember, the material is silk.
