I'm 5'9'', have a 38" hip, 28" waist, and am 140lbs for reference. I originally went off the sizing chart and got the medium. This past season was my first snowboarding (never been skiing either) so it was safe to say I'd start out spending quality time on my bum. Knowing this, when I received the medium, yes it "fit" standing up straight but it was pretty tight around my thighs when i started bending my knees and tried sitting down. I decided to return and get the Large. The Large fit perfectly with some tightening of the waist straps - it fits exactly like the model's below in the tan oxford pant does in the first couple of pics. This does not line up with the sizing chart at all really cuz according to the chart I should be between a small and a medium...I really am glad that the Large ended up fitting because these pants really are that perfect combination of a loose street wear fit with some subtle feminine curves. With how much time i spent on my butt this season, I never had an issue with snow soaking through and I always felt warm with only a thick ankle length yoga pant under. The length of the pant is perfect as well! I'll definitely keep coming back for these and hopefully there will be new color additions in the future!
