I see what you mean, from the knees down they are pretty baggy.
The size 33 NS have a 11.75" thigh, an 9" knee and an 8" leg opening.
The size 33 PS have a 12" thigh, an 8.5" knee and an 8" leg opening.
If you were to get a pair of 33 PS, the thigh would be slightly bigger, the knee would be a 1/2 inch small but the leg opening would be the same.
... problem is calves are somewhat disproportionate. Just like thighs...hip bones ...poster child fr disproportionate and squatting doesn't help. I want more form fitting, especially from the knee down without being like a second skin and exposing curves..
Width across calves is about 7.5 ... that's what I want the leg opening to be...
I don't wear this type of ensemble, I was chilling in sleepwear then randomly decided to throw on any footwear I could find, grab the tripod and go out for a quickie...
