I am so happy I just got back from my first fitting and the dress fit perfectly. Just needs to be hemmed. The stylist even said if I lose another 5-10 pounds it probably wouldn't need any additional alterations, of course I don't think it is likely that I will lose 10 pounds in the next 6 weeks.
Here's a picture of me during the dress shopping:

And today during the fitting. I definitely see some differences in my stomach and arms.
