When you want comfort, want to lounge around, dont' want something heavy and bulky, these are IT. Amazingly comfortable, soft and silky. Very lightweight, but provide enough warmth for inside comfort, or perfect wear for a 4th of July night. Purchased these in large, my measurements are 31, 38. They are snug, not tight, on my thighs, but they have some serious size to them and most pants run snug on me there, anyway. Length is pretty long, I stand just under 5', so these are exceptionally long on me. They have a loose fit, and really just couldn't be more comfortable. Vibrant, true colors. I turned around and purchased another pair for my daughter and she loves them just as much.
