At first I didn't care for it before trying it on due to the look of polyester. Once on I did like it. It's very sheer- for instance a freckle may show through however can camouflage the underarm. I normally buy a medium sometimes a large. I went with a large and glad I did because the large fits me a little loose so it's not binding around my arms. 5'3" 147lbs 36D
