Hip dips occur where the skin attaches to or attaches to the deeper part of your thigh bone, called the trochanter. These signs are more prominent in some people. It is due to the amount and distribution of fat and muscle in your body structure. Hip dips can be more or less noticeable depending on the width of your hips and the shape of your waist, as well as the distribution of your body fat. They can also be more obvious when you wear certain types of clothes.
