Do your pants have belt loops? In our opinion they should be avoided for few reasons. They detract from the formality of the suit, they interrupt its clean well-tailored lines, and most of all, they are uncomfortable. These are the reasons why tailors have created side adjusters metal tabs and adjustable buttons. They both draw less attention to the waistline, which is ideal if you are slightly overweight. The metal tabs utilize the pully system, and this is a smarter looking option. On the other hand, the button side adjusters are still smart, but they are just not as sleek looking and a little less adjustable.
