This is a two-piece athletic wear set for women made of breathable, stretchy material. Despite being stretchy and form-fitting, it is sized way too small for common sizes.Although it was very tight, it worked well for use as workout gear, including stretching. Because there was not a lot of material in the way, it was easy to have full range of motion and good activity.Overall this is a simple two piece outfit that is a little on the snug side but still gets the job done for activewear, especially high demand activities such as working out.
