I had my mom measure me before purchasing and we decided to go up a size per the details section on the description of the dress. And I will also be 8 months pregnant for my sisters wedding. I also ordered the petite as I am 51.

The dress is huge. I put it on and it was literally falling off me. The straps needed to be taken in a lot more than I expected. The flutter sleeves came down past my elbow and were basically hitting my forearm - incredibly awkward. The built in bra cups are stiff, awkward, and not flattering. The pleating on the skirt is too much- it makes me look like a sack of potatoes. The only part Im not surprised about is the hem- I expected i would need to hem it.
