Ali 4 Wore these leggings for the first time at the gym. Dance class, aerobics, lots of burpees and moving around.... WOW! these leggings did not disappoint. I was shocked at how well they held up. They moved SO WELL with my body.... No sliding... No readjusting...I was so sweaty. I thought "ew.. these are going to be gross".... But I was shocked... I went to the bathroom and took them off and the fabric was COMPLETELY DRY! :O wow... The only thing that got slightly damp was the actual elastic in the waist band.I also LOVE the rediculous amount of STRETCH these pants have. There's no way these can't fit you. When I held them up after opening the package I thought: "crap.... These look so small... I got the wrong size"But they slid right on perfectly.. it felt so comfortable, like nothing was on ^^3 small complaints:1.) The color/design is not as rich and vivid as the pictures show... Maybe it's because I'm too fat? It's stretching out the pattern /design.. and the inside/underneath of the fabric is WHITE... So as my body/fat stretches it out, it becomes white-ish/lighter.2.) This is only my first day wearing them, and the very first time I went to the toilet... I slid them off and heard a *RIP*!!! :O now theres a small bit of lose string on the seam by my waist :( im so sad... Im not too big for the size.. and I didn't forcefully rip them off. But they're already broken :(3.) Wish the waist band was a solid, thick, compression band instead of a very small, thin elastic band going across the very very top (you can see from the picture)?+ The size is perfect. I'm 5'7" (170cm), 135lbs (63kg), and my hips are about 40in. (100cm) and my waist is about 27in. (68cm).
