I used this for about two weeks after liposuction on my upper arms. I also had a bolero type, but this supporter type was easier to use. There are no noticeable stains, and there are no problems with use, but please refrain from purchasing if you are concerned about minor imperfections. The size is SS. It's best to have this as a spare if you are going to have liposuction! *If you are planning to have liposuction in the future, we recommend going two sizes down from your usual size!
