Update:

OK, I tried the dress on again but this time with the pantyhose and shoes I'll be wearing and I just have to say: I LOOK TOTALLY HOT!! I love love love love my new dress! And love love love how I look in it. And that was without my hair done and no makeup on. Yea! Who cares what freakin' size it is!

And, I also managed to make my Halloween costume and it turned out really well. My sewing maching held out for the one seam I had to sew and the rest didn't need any sewing. It's going to be really cool!
