Material is good. Tight. Stretches as needed for the gym. Not autumn high, I do not cover the navel. You can pull on the navel, but they will come down later anyway. This is not a minus, wrote in order to know. I ordered it with the top, but I did not like it. Sits not beautiful, sticks out behind the neck. Although in other photos in the reviews did not see such problems. Perhaps it's because I have a chest like a boy))))) delivery 17 days, and during my order there was a New Year's weekend.
