A blazer is a formal wear for both Men and Women . When it comes to Men coats become more formal wear as it is an evergreen formal wear than blazers whereas for women blazers is most suitable for ladies as formal wear. However the blazer are a step lower than the suit jacket. It is a hybrid of sorts because it is more formal than a sports jacket but unlike the suit jacket, a blazer is not made with a matching pair of trousers. Blazers have a looser fit compared to suit jackets also not as structured especially in the shoulder area.
