A body type is characterized by petted shoulders, small breasts, a narrow waist and flamboyant hips, as well as a round butt or thick thighs. The so-called centre of gravity of the body is lowered at the thigh and pelvic points. Usually, the lower part can be a couple of size numbers larger than the seated clothes on the upper body.
Body types are classified by various means. Classifying body types is not a scientific approach, but the purpose of body types is to help and facilitate people when choosing clothes such as jeans. This is also one of the reasons why clothes of the same style on top of people of different models don't look as good.
