Turquoise & Black Polka Dot "Caprice" Swing Party Dress with "peek-a-boo" back. This circle skirt dress was first designed in 1957 by Simplicity Patterns. The demure curved neckline belies the sexy Peek-a-boo cutout back. In addition, the full circle skirt flows beautifully as you twirl around the dance floor. Add a petticoat for a more traditional look.
