I've worn this dress about 6 times now and all is well. My favorite part is the wonderful black slip underneath, that you can remove, so I have used it with other dresses I have (brilliant!) The dress itself is sheer, super light and floaty, doesn't wrinkle, and washes up like a dream. Sleeve are also very generous. I'm a 42DD and the top fits perfectly if not a wee bit fitted. My hesitation is the vertical lines and the dress doesn't come with a belt. I have paired it with a think black leather belt and it works, however the waistline where the fabric meets is higher than where my belt wants to sit. I have to adjust it through the day and tug the front of the dress down, if that makes sense. Not terrible and overall I'm glad I bought this for work. My advice would be to purchase exactly your usual size.
