Disappointed But It's A Start

I spent the past two days cutting out pattern pieces, pinning pattern pieces, cutting material and then sewing most of it together.

Everything was going fairly smotthly until I tried my dress on. 

Wow it looks like a tent, or rather it makes me look like a tent trying to hide a pregnancy.  Ergh.  I'm so not pregnant.

Now I'm not sure if I should start again and see if I can cut a smaller size or try and take up some of the slack in the side seams.  Both options seem like too much hard work right now.
