Do you ever wonder why pants size is never the same as you try on pants from different brands? The good people at Esquire was nice enough to look into this and measure the actual waistline of pants from some of the most popular brands in North America. The worst offender is Old Navy whose size 36 pants measure a whopping 41". So if you shop at Old Navy or one the other don't-know-how-to-work-a-measure-tape brands and think you know your size, THINK AGAIN!
Notice how the more "generous" brands are also often the more popular brands among the general public.
