These are great. I wear them for yoga as well as for running errands. Good thickness and the rise and length are perfect. I'm 5'3", 110 lbs and ordered a small - they have a little room in them as I don't like them super tight.
I am a active, working mom with a massive need for versatile clothing. I love these leggings! They are so versatile. I wore them to Yoga and then dressed them up to go to dinner in the same day. They are reversible, which is a really cool feature. The fabric is a nice weight and feel. I am 5'5 and ordered a S. The material cinches a little at my ankle, but not so much that I feel I need to get them altered. They don't ride down while sitting/standing or practicing yoga. I'm thinking about ordering a second pair already.
I have had multiple pairs of the original black Zella Live in Leggings and these appeared to be similar in look/price, but buyer beware these are NOT THE SAME. They are far inferior. As some other reviewers have said, these are a lower quality thinner material, more see through, and constantly fall down at the waist after taken even a few steps. Unfortunately, I had already taken off the tags (because they look exactly like the originals which I love), and I cannot return these.
Hands down best leggings ever!!!! I've never reviewed clothes before but these deserve it. I have slimmer hips so I have a hard time keeping leggings from sliding down; these leggings stay put all day long! Don't waste your money on more expensive leggings. I wear a size 25 or 26 in denim (AG, Jbrand etc.) and the x-small are a perfect fit for me.
