Runs small in the waist
Size: 34, Color: Black With Black Strip
These are good pants, but as other reviewers have noted, they tend to run small. Order one size up from the size you normally order. I'm a 34 inch waist, and I ordered the 34. They were tight, and I had to have them let out. I may order another pair, and if so, I'll order the 36. Don't be vain. Be smart.

Good value
Size: 40, Color: Black With Black Strip
My husband and brother in law both found these pants to fit a little smaller than regular dress pants.....mostly they were tighter in the thighs but the length/waist was perfect. They each ordered a size or two up and had the pants tailors to fit. They looked very sharp and were of a good quality considering they were not super expensive. I hope they have the chance to wear these more often!
