Buttock Shapes and Types: Personalized Buttock Contouring & Trending Buttock Shapes

There are 4 main buttock types mentioned across all sources on the internet:
Heart-Shaped: The buttocks are full on the sides, accompanied by a slim waist.
H-Shaped: The sides of the buttocks are not prominent, and the waist-to-buttock transition is undefined.
V-Shaped: The upper outer area of the buttocks is prominent, accompanied by a slim waist curve.
Round (O-Shaped): A more balanced buttock shape where both the slimness of the waist and the sides of the buttocks are clearly defined.

So, what are the trending buttock shapes recently?
Round Buttock Shape
V-Shaped Buttock Shape
From Dr. Mehmet Haşim Güner’s perspective, these classifications are not evaluation criteria for achieving a better surgical result.
In my nearly 12 years of surgical career, I have seen people from all nations. Frankly, there is no distinct buttock shape like textbook information. That is why I would first like to share my own classification with you.
1. Male-Type Buttock Shape (Flat from the back and hollowed from the side)
Unfortunately, this is the most disadvantaged group. In these patients, there is almost no transition between the waist and the buttocks. Even if their shoulders are broad, the buttocks cannot match this width, resulting in an extremely small and flat buttock shape. Likewise, there is an empty area forming an obvious hollow on the sides of the buttocks.
Since the weight gain pattern of these patients is also masculine, if they gain weight, they develop an extremely bulging and hard abdomen due to visceral fat accumulation.
In these patients, the body shape must first be clearly explained to the patient, and they should be kept away from exaggerated expectations. In fact, information stating that another fat injection for buttock enlargement can be performed in the future should also be added.
First, the waist and abdominal area should be exaggeratedly slimmed, and the harvested fat must primarily be injected into the side hollows of the buttocks. Afterward, if the amount of harvested fat is sufficient, it should also be injected into the upper parts of the buttocks to make the waist-to-buttock transition more feminine.
2. Hip-Dominant Buttock Shape
The buttocks of these patients do not look very small from behind due to significant hip (basen) support. Since weight gain mostly occurs in the leg area, their waist area is not excessively thick.
I personally call this shape the European body type. In this female body shape, the waist area always looks slim in clothes, but the legs are very thick in terms of fat accumulation, and the appearance of cellulite is more prominent.
In these patients, the buttocks should not be enlarged excessively; instead, the deficiencies within the buttock region itself should be evaluated, and fat injection should be targeted toward those specific areas. For example, if the upper side of the buttocks is empty, fat should be added to that area, or if the back of the buttocks is somewhat flat, fat should be added there. If an excessive amount of fat is injected into the entire buttock area, future weight gain may cause excessive growth in the buttock region, which could disturb the patient.

3. Combination Buttock Shape
Since these patients gain weight easily in the waist area as well, the transition between the waist and the side of the buttocks is undefined. There is usually an empty space on the sides of the buttocks, and the back of the buttocks can be flat or slightly prominent. The hip (basen) area is not excessively large, but there is still a slight weight gain in this region.
In terms of contouring, the waist and abdominal area should be slimmed down, fat should be injected into the side areas of the buttocks, and alongside this, if necessary, light liposuction should be added to the hip area and to the upper side of the buttocks if it is more prominent.
Evaluating the Contouring Processes:
Combination Buttock Shape:
This is the group that can be made to resemble the round buttock shape the most through a buttock fat injection procedure. Following the surgery, a slim waist is accompanied by a buttock shape that has both natural contours and full volume.
Hip-Dominant Buttock Shape: I
f a patient wants a Kim Kardashian style or an exaggerated buttock shape and possesses this anatomical structure, this is the easiest patient group to fulfill that request through fat injection. An hourglass appearance is accompanied by a wide lateral buttock fullness extending from the upper outer buttock down to the lower hip area, making these patients stand out in any outfit and setting.
Male-Type Buttock Shape:
These patients are the group that needs buttock fat injection the most. Almost every surgery improves the buttock shape and provides a more feminine appearance. They won't have an excessively large buttock, but the perception that the buttocks remain small relative to their existing body lines, as well as the shoulder-to-buttock width imbalance, will be corrected.
Ultimately, the shape of the buttocks is personal, and contouring should be done according to what will make the individual happy. At least, that is the case for me.
When determining the buttock shape, it is necessary to conduct a detailed analysis to ensure that the patient's expectations are understood as clearly as possible. Buttock volume influences many things, from clothing choices to social perception and becoming a more striking woman. I find it healthier to draw a detailed plan based on the person's lifestyle, dressing habits, and social environment.

What Are the Trending Buttock Shapes Recently?
Between 2020 and 2024, buttock shapes with extremely prominent contours that were larger and attracted extreme attention from the outside were trendy. You can think of it like the Jennifer Lopez buttock, etc.
Today, a more natural and not overly exaggerated, yet rounded and full buttock shape is in higher demand. For this reason, very slim women also do not hesitate to undergo this procedure.
In fact, buttock shaping is also performed by selecting specific areas even in women with very little fat, tailored to their requests—a technique named "skinny bbl", which I also covered in my article "Next Generation Buttock Contouring with Skinny BBL".
