Butt Shapes

We’re proud bra and breast experts here at True&Co., but we also know our butts and butt shapes! We already know our bodies are different and unique, and our butts are no exception. There are many different types of butts, and knowing which one yours is will make it easier for you to pick out the best underwear that will fit and flatter your butt shape. 

So, what’s behind your behind? Physical fitness and lifestyle aside, butt shapes are determined by a combination of things: the placement of your hip bones, fat distribution, the size of your gluteal muscles, and the way those muscles attach to the thigh bone. Not as cut-and-dry as one might think.

As a sidenote, ladies: don’t worry about any cellulite, stretch marks, or jiggle in the butt and thigh areas you’ve tried to get rid of. We’ve all been there and the truth is, they are all biological normalities! There’s no reason we should see our curves and skin as “problem” or “trouble” areas so don’t!

Anyway, back to butt shapes. We’ll identify the five most common butt shapes to help you in your underwear search. Keep in mind that there’s also a lot of overlap in characteristics between these butt shapes.

A-Shape Butt

“Pear-shaped” women who are curvier in the thigh area tend to have A-shaped butts that widen below the hip bones.

Best Underwear for A-Shaped Butts:

This butt shape tends to stem from fuller thighs, so the most comfortable underwear styles for A-shaped butts are ones with high-cut legs and larger leg holes. Opt for high-cut panties, tangas, and bikinis. When you’re in the mood for boy shorts, go with ones made from stretchy lace or seamless, laser-cut edges which will be more comfortable for your shape.


Round Butt

Round butt shapes are pretty self-explanatory. Their shape is due to fat distribution around the cheeks of the butt – including the upper portion. Round butt shapes usually sit high when viewed from the side and have a fuller look.

Best Underwear for Round Butts:

Round butt shapes need a little extra coverage in the back to prevent the front or crotch area shifting backward. The result: a wedgie either in the front or back (or even both!). Tangas, thongs, briefs and boy shorts are ideal for contouring round butt shapes and cheeks.


Heart Shape Butt

Heart-shaped, or upside down, butt shapes have more volume (fat distribution) in the lower part of the hip and thighs. 

Best Underwear for Heart Shaped Butts:

High-cut leg holes might not give enough coverage for butts that are fuller and sit lower, so go for briefs, boy shorts, hipsters, or bikinis with a lower-cut leg opening.


Square Butt

Square, or H-shaped, butt shapes are due to higher, more prominent hip bones or a distribution of fat in the “love handle” area. The overall appearance of this butt shape is straight up-and-down right below your waist, rather than tapering to the waist with a smooth curve.
