. 100% polyester. I typically steal away from polyester, however, there are some polyester materials that seem softer and this is one of them. It looks like the photo. no smell. If you have a large bust you may want to size up. I have large. 38DD it’s a tad fitting in the bust area. But it doesn’t look too tight while wearing.. Definitely better quality than I had assumed. It seems well made not cheap.
