Hi I am female and recently purchased the Skinny Lin in Dry Steel. My measurements: Waist - 25 1/2", Hips - just over 33" I sized up and got the jeans in size 29". The main reasons for this were: - I previously got a pair of Grim Tims in 27" and could barely do the button up, found the thighs too tight and they were too loose from the knee down - I wasn't looking for a super-skinny skin-tight fit but just a very slim fit, particularly from the knee down The 29" is the perfect size for me. As they have stretch, they still fit me really well in the waist and I don't have to wear a belt or anything and they don't slip down. They are tight enough at the ankle and I prefer to turn them up. I also have them in 28" and there isn't a huge difference, they are just slightly narrower all over but still fit great.
