The foundation for the ballet costume is the leotard. I use bias cut silk satin ribbon stretched over the torso and cut to size and shape. This is glued to the porcelain with a very thin line of Tacky glue at the edges of the fabric.
To form the under skirt two layers of silk tulle were gathered at the top edge, pinned into soft pleats and steamed to hold their form. ( I covered a 1/2 inch dowel rod with cotton batting and fabric to make a "shaping pole" )
