I am 160CM, 48kg got it in S.
It fits like a glove, and the material is so soft and fluffy. There's a little pocket at the back of the leggings which is useful for small things It is definitely one of the cutest fitness wear I own. Worth it!
First time I actually enjoy wearing tights as usually the ones I wear makes me uncomfortable and feels like its going to break everytime I stretch but Livlola's tights is durable and comfortable. Will definitely be recommending this!
