I always am a little leery of buying clothes online since it doesn't allow me to try them on. I used the sizing chart on the site/page and it did help get the size that I would have most likely bought if purchased in a store. It just seems like the very top of it is sized a little larger than it should be compared to the rest of the shirt. This isn't a huge problem since I typically have a tank top underneath everything anyway. I love that it gently flows over the stomach area. It is nice to be able to have a nice looking shirt that isn't fitted. It hides the buldges and is super comfortable. Plus it looks great.
