Rita, I would wear this size. I sort of slammed it on and took photos - if I were really going to wear it, I'd fix the tiers so the stripes weren't all wonky around my boobage. I feel very Russian in this dress!
I am hoping to be no bigger than the size I am, and hopefully lose a few pounds, so as long as I don't gain, this size could work. I'll have to decide if I can move past my belly hangups... you all are really helping with that.
