Run small, size it up
Color: Mushroom, Size: 32W x 30L, Color: Mushroom, Size: 32W x 30L
They go small, Im 5'8", 165lbs, usually 32x30 fits just rigth in most brands Levis, Izod, whatever, can't even close the zipper on this one, my dingus prints in the front if I manage to close it, I will try a 34 or even 36, if you want one, size it up. Length is right.
Anyway, the pant is good, sturdy looking material, is not soft but nothing uncomfortable probably gets right after break it in, reinforced stitches on pockets. I think they would work great for a technician, salesman or an engineer, those jobs where you have to look like a human being with a polo shirt but sometimes needs to do something without ripping your pants while crouching or for daily abuse of the regular Joe, will try another that fits

Good, but size up!
Color: Black, Size: 30W x 29L
These are exactly what I wanted, but as many have stated, you need to size up. I found that going up two sizes (from my usual 28 to a 30) made for a great fit. I love that they come in a 29 length. One anything point is they came with creases in them from being folded in the package for a length of time. I had to steam and press them before wearing. I’ll likely buy them in other colors.

Great Pants
Color: Khaki, Size: 46W x 32L
Great pants but buy one size up in the waist. They are well made, comfortable, and good looking. They are Dickies brand what more needs to be said.

order 3 or 4 inches up than your usual waist, run very small in waist
Color: Charcoal, Size: 33W x 30L
arrived with dirt on the bottom legs but amazon helped with that. anyway I weigh 115 lbs and am 5'8 and I am a woman. I know that Dickies these days run super small for their size, so it sounds insane but order up 4 inches than your normal waist size, then run small in the waist and they will shrink a size with a few washings. I ordered a 33 waist and they did shrink probably a size in one wash lol! they are still a bit loose in the waist but not big and I know with a couple more washings they will be just right. I do not like anything skinny fit or with no give. but yah, I love the charcoal gray color, one of my favorite colors, much cooler than plain black. I normally enjoy the Dickies shorts but with these forty something degree afternoons these are my new go tos. I am not a jeans person and I sure as hell with not be wearing pajama pants out in public like these dang younger adults lately.
