I bought this dress in black and it's gorgeous. Based on previous reviews I purchased a size down and that's the best way to go. I normally wear a 12, but the 10 was perfect. The dress is very comfortable and can be cute with flats and sexy with heels. It's the best little black dress you can own. I didn't find the need to wear a slip with this dress, it's not see through to that degree. I love it. Thanks O!
