Absolutely beautiful dress, but unfortunately I needed to exchange it as the sizing wasn't as I expected. I followed the sizing chart and then sized up based on other's reviews, and I believe I would have been fine just sticking to the chart. However, I have narrow shoulders and am pear shaped, so that may have added to the loose shape. For reference, I ordered a size 6 and usually wear a US 4, but do have an issue with a fair amount of standard women's sizes feeling wide at the bust.
The dress had boning channels in the bust and a rather full attached petticoat so it feels best suited to a special occasion. The outer fabric was also a bit more stiff than expected, but the dress was lined with a soft fabric that would make this comfortable to wear had I kept it. The stiff fabric also made it a bit difficult to adjust the straps, but they did adjust to quite a range that did help with the fit.
