Both genders have the same problem. Women get underwear in exact sizing, along with tops that usually are exact. Men get exact sizing in pants and button up shirts. Women do have the same problem with sizing of pants and dresses, but women also have a vastly larger selection. Go look at how many stores sell only to women. Then go look at the stores that sell to both but then have a women’s section that is 5-10x the size of the men’s section.
