Vintage dritz my double dress form w/ plastic coated snap button metal wire mesh fitted corset & collapsible adjustable rod. This form was innovative for its time, the removable wire mesh corset is adjustable and was placed & worn by the woman for her exact fit & size. I would say it's a small to medium size.
Closer to a smaller size. Adjustable metal rod: 53 inches tall adjustable rod lowest it goes down. 18 inch x 18 inch bottom base. 17 inch long shoulder to shoulder.
14 inch wide bottom of form. Condition: the metal adjustable rod has black tape on the top end. The top back snap button is broken. This item is made of metal and plastic.
