I admit I was very skeptical fitting, on top of that I was afraid that it is not expandable (certainly not enough for my body because I took a little weight after my pregnancy and I approach most of the L of M). But it was a very pleasant surprise when I saw that I was fine, but in pulling it, as well sticking to implement. Result: 6 hours a day with abs, zumba and walking, my skin is softer (even my husband has noticed). I think it fulfills its contract leggings! And for washing: hand, you are sure to keep longer effective!
