I wore this dress to my oldest son's wedding and received many, many compliments. My favorite? "That's not a dress, that's a statement." The wedding was outdoors in Florida (in AUGUST!) and I was still very comfortable. It was also very comfortable to dance in. It's so pretty. I would buy it again in a heartbeat.
I am 5' 6" and weigh 137. I ordered a size 6. It fit perfectly.
