I'm 5'6" 120, waist 26, hips 34. I got size 0. These are SO flattering. Somehow they're snug in the rear and through the tips but unstructured through leg and thigh and I don't get that weird front fold thing that happens sometimes. I'm really pleased with these and just bummed that I discovered t...hem so late in the season because they're sold out of every other color... I would definitely buy more. Fitting notes: I'm short waisted so these mid-rise fit me like a high rise which is fine and what I expected (rise in the size 0 is about 10"). In terms of sizing for pants I'm usually between a 00 to size 2. I'm slim but slightly pear shaped (and short waisted) so regardless if I'm doing a skinny leg or wide leg pants are usually more flattering if they're fitted through my waist and hips. And these hit all those marks. (For comparison I also ordered the size 2 but will be returning because they were loose in the waist- they fit everywhere else really well but waist was...funky. Almost like they were floating. The size 0 felt a tad snug initially but after just a day of wearing they've already stretched a bit and now fit like a dream. Also, my experience is that MOST twill/jean materials will stretch with some wear so I usually size down rather than size up and just make sure that I line dry them the first few times I wash them).
