I wish I would have paid more attention to the other reviewer. Although I think the dress is lovely, it runs very large. Probably 3/4 of my closet is filled with BCBG size XXS clothing, all of which fit beautifully. Not only was this dress very large, but the opening at the side plunges down the entire side of the dress. I looked in vain for a hidden snap or hook and eye, but there wasn't one. I'm not sure how you could keep the side together. I gave the dress to my sister, who wears a size small, and although the top part of the dress fit, the bottom was too snug for her. She couldn't figure out how to close the side opening, even with a belt, as it was portrayed on the model.
