On the quality gray I liked more than black, they do not see pile, which clings to the fabric. Through the time in the black on the seam on the buttocks there were small holes, gray while whole. Very comfortable. On the belt is tightened with an elastic band, which is fixed with a button, you can loosen or tighten
Quality is super!!!! I took the size of which I take and before pregnancy. M sat very well, there is where to grow the stomach. I regret that I did not order several at once. It's late now, while they're going to have to give birth and it's hot in the summer.
