This dress is really stunning. So much prettier even than it looks online. I'm an Aus/UK 14 at the moment (US 10) and went with the large - it fits, but only just. Around the waist is fairly snug. The cut is feminine and very flattering. The sleeves are pretty, the just-below-the-knee length is chic, and I didn't have the problem with the bust/neckline like the other reviewer did. I'm a 34E, and the L for the bust beautifully. It also wasn't as low cut as I was expecting judging by the picture, which is great. It's lined, and the lining stops where the ruffle around the hem starts, so it's almost full-length. The skirt has a lot of volume, and swishes nicely. The fabric feels lovely, almost like a matte silk crepe, but not too think, so perfect for an Australian summer. I plan to wear this on Christmas day. If you're on the fence about this dress, get it. It looks so much more expensive than it is.
