I am going to a black tie ball and still have a heavily baby body (big overhanging icky stomach!) My boobs, which are normally large are utterly huge from breast feeding. I am normally a size 10-12 and I am probably a 14 at the moment.
I have good legs, so I don't really want it to be long (just above knee would be perfect).
On top of that it has to be a good price as I'd really like to think I'm going to lose this weight so don't want to blow my budget on something that will be too big in two years time in a few months.
