For starters: my size:  I am 5'10" 137.8 lbs  In many brands I'm usually a small/medium or 4/6.

I do love the pants when they fit but the sizing is weird and there is a lot of shrinkage.

I read other peoples reviews and many didn't have a shrinkage problem so I don't know what the difference is.  (I washed in cold water, then low heat setting on dryer. Now I let them air dry)

I ordered a Medium 34" and could barely get them over my knee. Sent them back and bought a Large 34". They were perfect until I washed them. they shrank to be smaller than the medium. Bought a XL, washed them, they shrank to a fitting size.

I have them in 5 colors now, all XL 34".
