Did you know that jeans became more popular during world war two because men were wearing them as sturdy work pants? Boot cut jeans are popular because they can be worn with a boot/high heel. The leg on the jean was cut to be smaller than a flare but wide than a straight leg so a boot can be worn under the jean. These trousers are made to make a person look more slimming and tall. Although these types of jeans are more commonly seen on adult women, men wear them too. For men the cut is a little different because they are made for a work boot.
