Fell in love with these leggings the moment I saw them. The combination of workout tight and dress-up tight is just perfect. The zippers and sleek fabric make these so pretty and sexy and the fit is great for working out, the waistband might just need occasional adjustments if you are doing yoga. I am 5'2" and about 140lbs. I have the medium size which fits very well, I feel like these are stretchy/roomy enough that I might have been able to squeeze into a small but there might have been sheerness issues if I got them too tight. Love love love them!
