Uh...couple weeks ago, I purchased a black color black label Ralph Lauren suit. I was so focused on getting the right fitting jacket that I didn't really pay attention to the pants. A week after the purchase, I was half way on the other side of the world dressing up to go to my friend's wedding. When I put the pants on, I said, "What the heck?!" The pants had no belt loop. I was a bit taken by surprise because I've never seen it before. So now that I am back in the States, I am thinking about adding the belt loop. But my question is should I? I am 6ft 166lbs. All my shirts and pants are "slim fit." Is the no belt loop pants just fine?
