This dress is absolutely PERFECT for people who carry extra weight in their midsection and arms, like I do. I honestly have not felt sexy trying on any clothes since my weight gain, but this dress makes me feel that way!
There was a chemical smell on the dress when I got it, but I washed it in warm water by itself with scented detergent and it went away immediately.
The material is a stretchy material that you're probably thinking of, but it is thicker. I got the black dress and I will most likely buy another one in a different color.
Also, I bought a 3X and I am 5'3, 220lbs. It fits perfectly and I could probably go down a size or so, but I don't like super skin hugging clothes.
