Yikes, we are off to a 1920s theme ball. I'm size 16, pear shape, want to hide my arms and not keen on anything above the knee, and pastels wash me out completely. I was thinking about this, it has a hint of 1920s about it and I can dress it up with sparkly hair pins and ropes of pearls. Any other bright ideas? Long or short would be fine and I don't want to look as if I've tried too hard (no full on flappers please!)
