I am 5'1, 110lb and I looked like I was swimming in the XS size for these pants (this was the smallest size available for these pants in all stores I went to). I was so happy when I discovered the XXS size online, in petite/short. The pants were perfect EXCEPT--after about 4 months of wearing them, my first pair ripped at the crotch. I thought perhaps I wasn't being careful, so I bought another pair and was careful not to do any stretching (like tying my shoes). I washed using "delicate" cycle and air-dried only. Months later, another hole in the crotch. This time I thought perhaps it was the seller's fault (perhaps I purchased knock offs), so I bought 2 more of these otherwise perfect pants from a different seller. Sure enough, I just discovered a hole in the crotch for one, and the last pair I have looks like the seam is on the verge of ripping. These pants are just very thin and don't last very long. I wish they did last because they are the perfect fit (no flare, no dragging along the floor, low-rise, did not make my hips look huge).
