I was gifted these because they were too small for my sister. Ended up being too small for me as well. These are not the type of pants that should be "stretchy" but a slight percentage would be great. I'm 36-31-43 with 34" inseam. I'm only 5.6' &typically wear medium but, an XL would fit, although I'm not confident the cut would be flattering since I'm so leggy.
