I own two pairs of these leggings in XS and S, and honestly both fit great it just depends on the mood. When I want a more snatched compressive feel XS is perfect. When I�m in the mood for maximum softness and comfort S feels amazing.
For reference, I�m 5�3� tall, with a 26.8� waist and 39.4� hips. The length works well for me the leggings hit about 2.5 inches above the ankle.
I wear these for squats, lunges, and treadmill workouts at the gym and they perform great. They stay in place, feel comfortable and move well with the body. I�ve had no holes, thinning or noticeable wear.
I did notice a slight difference in fabric feel between colors. My Elemental Pink pair feels a bit softer while the Iron Stone pair feels smoother.
