^ actually, I have worn it less than 5 times. It's still very new, feels pretty rough.
I tried 30w first (my usual size), but the thigh was so tight, it was uncomfortable and it hurts when I move around. So I exchanged it to 31w. But I'm regretting about this decision now. Since I lost some weight, the waist is big on me. Maybe that's also why I haven't worn it that much.
