Reasonable quality, slightly small, definitely unhemmed
Size: 42, Color: White With Black Strip, Size: 42, Color: White With Black Strip
If these pants are the right look for what you want/need, they're a reasonably good quality option. But that said, in practice these looked a little "cheesy" with the black stripe. I can't say for sure that's a result of how the product is made/how it looks, but I just couldn't see myself wearing them. That's assuming I could wear them... In terms of fit, they were slightly small in the waist for both pairs I ordered. I'm not sure what I thought they meant when I read that they were unhemmed, but for those looking for pants to take out of the box and wear... these aren't for you. The ankles are not "finished" and require hemming to make them look acceptable. (This was my fault, so I didn't count off for this)

They stand out, and are flashy, but sizing is complicated.
Size: 34, Color: Black With White Strip, Size: 34, Color: Black With White Strip
High-quality pants and flashy. The stripe adds a lot of attention for reasons both good and bad. The materials they were made are excellent quality. Pants are thick, but not too thick, and are lightweight, guaranteeing easy movement. Comfortable - could wear these all day. I do love their appearance. They made me feel like a million bucks. :) The only problem is sizing and fit. I normally wear size 34 for waist in jeans and dress pants like these, but the 34 I got didn't fit at all - too tight. So, I ordered a 36, and it fit, but barely. When I sat down, there was too much tightness in my "masculine area". I also ordered a 38, and, well, they were just too big - practically hung off me. A 37 would probably work for me in these, but they don't offer such a size. I have to return the 34 and 38. Will keep the 36, see if I can have it altered in some way. Length was fine. Being 1.86 meters, often the length in these pants is a little on the short side. In the photo, I'm wearing size 36 and the black pair with the gold stripe, which is actually more of a flashy yellow. I liked how I looked in them, but they were a little too tight at times, the belt wasn't even necessary. It enhanced the outfit though, don't you think.

Good as a standard "Tuxedo" pants
Size: 42, Color: Black With Red Strip
Red Striping could be wider. These are good as a standard "Tuxedo" pants but if you are looking more fore a "Security Guard" style pants the striping needs to be wider.

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.
