Very well structured, slightly stretchy, and the fabric is a heavier denim. I usually purchase XXL at BR...but I got the longer version of this dress and the XL fit and was very roomy so I thought the same for this. I was wrong. This dress is more fitted so if you have a large chest you may find your regular size more fitted. Also, its more A-line with a smaller fit so you might need to go up a size for the billowy effect. The sleeves are huge but nice and stays structured as seen on the model. Over all, its a nice dress and I am going to keep it as I do plan on losing a few pounds anyway. A great buy.
