Women's 50s Vintage Short Sleeve Pleated Swing Dress white
I'm generally a medium but I used their sizing chart that was provided and I got a large and it fit me perfectly. That being said, you'll wan't to probably wear a bodysuit under it or something so you don't have any bulges because it is so stretchy. A 26" petticoat also works perfectly. On note before you buy- You can't dry this but you can hand wash it.
