I bought these pants and its matching sweatshirt in two sizes. The size S in Charcoal is super comfortable for home-wear. It's a bit frumpy around the ankles because I'm short, but I don't mind it since I wear them mostly at home and walks around the neighborhood. I also got the Dark Taupe in XS to wear out (park, grocery runs). The waist fits comfortably even when I'm bloated and it's not as slouchy/baggy as the S size. The fabric is really soft and I find the Dark Taupe stayed pretty fleece-y even after washing, but the Charcoal feels like it got a little thinner, which worked out in my case since I wanted to use it for summer nights. I'm using the Dark Taupe now since fall weather is setting in and it's perfect for a walk in 14-16C temps. I'm 4ft 11in and 105lbs.
