I often wear a 10 or 12 pants size, and during the initial testing period, I gained muscle and lost weight. I wore each piece at least twice, both around the house and outside and about running chores or attending events. I definitely bent down, lasted, squatted, used the bathroom, sat down, walked around, brought them up and turned off, attach and adjust any belt, and often wear pieces like I do in everyday life. I checked the comfort, prolonged, whether the pieces rode up, rolled or slid down, whether they were easy to breathe, and the silhouette of the applied pieces looked like a tight skirt. Next, I will test more brands including Spanx, Skims, Victoria's Secret and some affordable price options from Amazon.
