Ladies, this dress is absolutely gorgeous, especially at the sale price. There is absolutely no stretch in the fabric and it's lined in a teal polyester with no stretch so even if it did have a slight stretch, it wouldn't stretch due to the lining. I normally wear a size 2X, however, when I read the previous reviews, I knew it would run small so I called customer service. They told me the dress runs really small so I ordered the 4X to be on the safe side and the bust was still too small. It was an easy inexpensive fix, I just had to lower the zipper by an inch and a half, tack down the fabric and put extra darts in the top part by the arm hole and it fit like a dream. This dress is AWESOME but it seems to be running two sizes smaller than Pin Up Girl House Brand dresses.
