I'm 5'9" & I weight 135, I bought these to wear over my legging, since I have a long walk to the store and bus stop. It's about 14 to 16 blocks to the bus stop. When it's 14 to 25 degrees outside, it's hard to stay warm waiting on the bus. Even with a down coat, my legs still get cold. The only way to stay warm while waiting on a bus, is to have extra layers on. Even with Silk long underwear under legging, it's still not enough to stay warm on a cold windy day waiting on the bus. Since, I plan on washing & drying them, I though Xtra large would be large enough after washing them, but after drying them in the dryer, they were more like legging. So I ordered another 2 pair, in a 2X, so when I washing them, I will still be able to get them over my legging, without feeling like I'm trying to put another pair of legging on, over my legging I have on. I hope this helps someone, but otherwise these are soft & very comfortable. Since I can't get them over the legging at the present time after washing & drying them, I'm using them to sleep in, since my apt is like sleeping outside in the winter in a tent. It's so cold in the apt., many of my neighbors have heaters. I wear sweatpants, long sleep T-shirt, sweat shirt over that, a knit hat and thick socks to sleep in. I sleep under 4 blankets. The bad part is when you get out from under the covers, it like you are outside, it's so cold. Using these as Pajamas works out great for me, because they are keeping me warm indoors. It would be really great if we had better heat in our apartments.
