Men's suit jackets tend to be boxier and you pair them with men's suit pants while women's suit jackets are more fitted to the body, more tailored, and cinched in places. When it comes to women’s blazers, there are more details such as the stitching. It is usually curled, more floral, or quilted which sets them apart from the men’s blazers. Many times, men’s suits will feature gold or silver buttons while women’s do not.
