How do you know when a jean fits you perfectly.
Jeans are tough to find a good fitting pair because leg size and hips and waist all vary from girl to girl. When you pull them on it shouldn't be a battle, if they don't slip on easily that means the legs are too narrow for you. Also the hips have to fit snugly and be wide enough while not being baggy. The hardest part is to find all of these that fit you and also fit the waist (where the fly and button are) and length. A good pair will slide on easily and not be a hassle to get out of or button up.
you just know. they slide on as if you had them tailored. They slide on you and you get a feeling, that its PERFECT! trust me, its happened tons of times to me =D
