I had these a year ago while I was deployed with the military and they kept me sane! I was working in 120 degree weather and these were the next best thing to coveralls. I didn't get the double knee this time, but they are still an exceptional pant that give me the range of movement I need to get underneath the aircraft and the coverage from all of the oils and fluids I work with. I keep reading reviews that talk about how unflattering they are, but they are actually comfy. I you are trying to use these to enhance your bottom then you might want to look at the other styles of dickies available; there are plenty! These are for WORKING WOMEN. I bought a size 10 because I work in snow during the winter and I wear  work thermals or sweats under them. Other than that I wear a 6 or 8 depending on my mood. Will always buy these for work; love love love them!
