I LOVE these leggings. I am 5'10 and they are long for me. The wide waistband cinches you in all the right places, lifts your butt and stays in place. I have purchased several brands and these are the best!
I'm 5'2, 115 and I bought the small. I ordered the small which fit, but they are too long. Not a problem since I plan to wear them with boots during winter. I also noticed they tend to get a bit looser by end of day but not too much that it's a problem. What I really love is how comfortable they are! The wide band make them flatten your tummy a bit if you are self conscious about it as I am.
These leggings are great - I've ordered multiple pairs and wear them with both casual tunics and dressy sweaters. And you can't beat the price. I would definitely recommend them. I'd say they are true to size. I typically wear a size 6 pants and the size S fits really well.
Based on the reviews, I decided to give these a try. I actually really liked them. I own s lot of Zella leggings and these are definitely a close second. They are thick and don't stretch through the day. Two key things I look for in good leggings.
