Today, women’s jeans have a more feminine cut and are generally tighter than men’s jeans. In the United States, they also tend to be sized by a single number such as 4 or 8(men’s jeans are sized by waist measurement and inseam length). In addition, manufacturers have adjusted their sizes as women’s body sizes have changed throughout history. Thus, a pair of jeans that were considered an 8 in the past may now actually be a size 4 or 6.
