This dress was made by my mom in 1976 for a bicentennial event. The dress is made from a double-knit fabric which stretches a bit. good for a 34" bust. There is no zipper so just foes over your head. I show it on a dress dummy with a 39"bust. was hard to get it on so a 34 is better. This is for petite. Great up to 5"2' with crinoline.
