I really liked this dress, but it was too big. I'm 5'7" about 140 and 34DD, and usually wear a size 6 or 4. I was told it runs small and they didn't have my size anyway, so I ordered up and got an 8. It actually fit me okay, but since the fabric is thick, it not being skin-tight ended up making me look 10 lbs heavier! One reviewer says it looks better if not skin-tight, but I have to disagree--it's not the type of fabric that is going to hang nicely and flatter. Plus there was a little bit of a pooch in the stomach (idk if that's from other people wearing it..?), which you can actually sort of see in the photo. If skintight, I could imagine this shape would actually enhance your curves, instead of making you look pregnant.
The part I liked the most was the top. Because of the lace-up closure, it fit me really well. I usually have a problem with corset tops b/c they are made for someone with a smaller chest, but this dress was perfect. Because of the lace-up closure, you can make it however tight you need. It actually is more of what I'd consider an old fashioned (real) corset -- the chest part is more straight/flat (but with the seaming it still looks curvy), and pushes you up a bit above the top. So this makes it not really molded to a certain cup size either. So if you're worried about a dress not fitting up top, it's a good choice. I think it would also work for a smaller chest.
It's more of a light pewter color, and not as shiny as it appears in the picture. The mauve seams are the same as they look in the picture, with the ribbon being the same mauve color. It's a really beautiful dress, and hopefully I will be able to rent again in the correct size! :)
