Turning 50, decided to have a bit of fun and do a 20's party. What do I wear? I'm about a size 8-10, but busty (32 G so normally need a 10-12 top). Would like to actually have a 'great' costume not just whatever I could turn up. Will almost certainly need to buy it from overseas (living on a small island). I'm terrible at visualising what something will look like on... help please!
