Unable to find women's work pants with enough depth in the rise to keep the pants up while I'm working and my frustration with the difficulty of finding women's pants the right length for my slightly-longer-than-average legs, I decided to try men's pants.  Lucky for me (and Amazon's returns department), I was able to try on my son's well-worn and many times washed Carhartts to get a reasonable guess as to what size pants to order for myself.  My first pair was a 32x34 B151 (son's favorite summer-weight pant) and after a couple of washings (very slight shrinkage).  They are comfortable for working, but just a bit baggy for the ideal fashion statement.  This was my second try (31x34) and it just might become my favorite.  They fit trimly and the spandex ensures that movement is free and easy.  A belt is necessary to snug them at the waist (I have managed to avoid the extra step of putting on a belt for decades) - I expected this with a men's cut - but (unlike the women's pants I tried) at least the waist is high enough that the belt actually holds my pants up.
