I am a petite and comfortable in an extra large and was hoping this was loose enough to fit comfortably with extra room to spare. I live in a very hot and humid climate thus the desire for room to breathe. I ordered the navy blue. It is colorfast and how. The material is practically see-thru. After the first wash, one can easily note that the fabric was not cut correctly for one of the back pieces as it shrank while the other piece did not. So, I am not happy about that, but with a little ironing, was able to make this work.
