Ruby Red Glitter Shoes Dorothys Wizard of Oz Costume Size 7. From the Halloween Spirit store, these Ruby Red Slippers will complete your Wizard of Oz Dorothy costume. I cannot tell if the size 7 tag on the bottom of the shoe is original to the shoe (see pics 10 and 11). From the end of the toe to the back of the heel, the shoe measures 10". Excellent condition. The red glitter has rubbed off a small spot on the top back of the right shoe.
