Bootcut: A boot leg is more narrow in the knee than in the leg opening. Manufactures often consider anything with a leg opening between 17 and 20″ to be a boot cut jean. However, it does depend somewhat on how wide the knee is. Bootcut jeans are always a good choice because this basic fit will always be in style.
Wide leg: This style is usually wider in the knee and the leg opening which makes it a slightly more relaxed fit through the legs. They usually have at least a 22″ leg opening. Wide leg jeans are a comfortable style that will look chic worn with flats or heels.
Flare Leg: The biggest difference between a wide leg and a flare leg is that a flare leg is narrower at the knee. Visually, there is a much bigger difference in the knee and leg given the “flare” effect. Flare leg jeans have at least a 20″ leg opening.
Straight Leg: Straight leg jeans have the same width from the knee to the leg opening hence the “straight” effect. Straight leg jeans can also be cuffed more easily that boot cut jeans when you want a different look. Their leg opening can vary from 14-16″ depending on the size of the knee.
Skinny Leg: Skinny jeans are the only style that actually taper in from the knee. They’re versatile and can be worn with flats, heels or boots.
