Very comfortable, however I should have got a size smaller.
These bottoms are amazing, I haven't worn anything else since they turned up! They are comfy, great light/soft material and flattering, and also true to size despite some of the other reviews. I am 5'6'', 62kg and a UK size 10. I bought a size S and they fit perfectly. The style is as they look on the model, fitted but not tight. If you want tight, buy leggings! I think I'm a little shorter than the model so they do come down a bit further than the picture (just above my ankles) and for me personally, I'd prefer full length but the length is clearly shown in the images so I wasn't surprised.
Absolutely love everything about this product.
