Vanity sizing isn’t the problem. The waist measurement on pants almost never matches the size on the tag, nor should it. That’s because pants usually sit below your natural waist, and your torso gets bigger the further down from the natural waist you are. However, the size on the tag is a “guess” about your natural waist size. Because everybody has a different shape, it’s not necessarily the case that pants that fit you have a tag size with your natural waist on it. That’s one of the complications with designing and buying pants: it’s rise dependent. Tl;dr though: vanity sizing is a myth
