Rigid sizes, real bodies. They don't mix.
Most underwear brands use generic sizes: XS, S, M, L, XL. Sounds logical, but in reality, it's often absurd: No body fits exactly into a chart. Maybe you're between two sizes? Maybe your body fluctuates – depending on your cycle, period, pregnancy, or simply how much pizza you ate last night.
Nevertheless, most brands expect you to fit into one rigid size.
The result:
- The underwear digs into your hips or buttocks
- The waistband rolls up or leaves marks
- It's too tight on your legs
- Or it's so loose that it constantly slips
And instead of thinking, "Maybe the underwear just doesn't fit," many women think, "My body is weird."
Spoiler: It's not.
How to tell if your underwear is too small
Many women wear their underwear too small – often because they think it needs to be tight to stay in place. Typical signs:
- It digs into your hips or buttocks
- The waistband leaves marks
- Visible lines appear under tight clothing
- The underwear bunches up or slips down
- You constantly adjust it throughout the day
- It feels uncomfortable as soon as you sit down
Underwear shouldn't occupy your thoughts all day. If you're constantly tugging at it, it probably doesn't fit correctly.
But underwear that's too big isn't the solution either
Many eventually just switch to the next size. But if the basic fit is wrong, that often doesn't help either. Underwear that's too big:
- slips
- wrinkles
- doesn't sit correctly at the back
- shows through clothing
- often feels "baggy"
So the problem is often not just the size, but the system behind it.
The real problem: underwear sizes often make no sense
Why can a woman wear an M with one brand, an XL with the next, and suddenly an S with the third?
Because there are no uniform standards. Every brand cuts differently. Some calculate extremely small, others large. Some orient themselves by clothing sizes, others by arbitrary values. In addition, slender bodies are still usually used as the benchmark.
Many women therefore don't even know their actual underwear size – because it doesn't really exist.
The Buttz solution: The 3-Size-System©
That's exactly why we developed the Buttz 3-Size-System©. Instead of 9 different sizes, Buttz only has 3:
- Size 1: XS–M
- Size 2: L–2XL
- Size 3: 3XL–5XL
The idea behind it: Your body shouldn't adapt to the underwear – the underwear should adapt to your body. Thanks to the extremely elastic material, it adapts even if your body changes: during your period, during pregnancy, or simply in everyday life.
So you no longer have to guess whether you're more of an M or an L. Check out our High Elastics Collection – that's underwear that adapts to your body, not the other way around. And if you're looking for period underwear: The Period Keeper also follows the same principle.
Why we believe the problem isn't your body
For years, women have been told that they are "between two sizes," have "difficult proportions," or "should really lose weight" for something to fit properly.
But most of the time, the body isn't the problem. The problem is that many underwear brands still design their products as if all women had exactly the same silhouette.
But bodies change. They are different. And that's exactly what underwear should be made for – not for a size chart.

FAQ
How do I find my correct underwear size?
Measure your hip circumference at the widest point and your waist circumference. Compare the values with the size chart of the respective brand – not with general clothing sizes, as these vary greatly by brand. With Buttz, you only need to choose between 3 sizes: Size 1 (XS–M), Size 2 (L–2XL), and Size 3 (3XL–5XL).
Why does my underwear dig in, even though it's my size?
Digging in is usually a sign that the underwear is too small – either because you actually need a size larger, or because the brand cuts very small. Inelastic materials can also dig in, even if the size is correct. Elastic material adapts better to body curves.
Is underwear that digs in harmful?
Constantly too-tight underwear can cause pressure marks, skin irritation, and a restricted body feeling. Especially on the thighs and hips, tight underwear can affect blood circulation. It's worth paying attention to the fit – comfort is not a luxury.
What does the Buttz 3-Size-System© mean?
The Buttz 3-Size-System© reduces the standard sizing system to 3 sizes (1, 2, 3), each covering a wide range of body sizes thanks to the highly elastic material. The goal is to eliminate guesswork in finding the right size and to create underwear that adapts to the body – not the other way around.
How do I know if my underwear is too big?
Underwear that is too big slips throughout the day, wrinkles, doesn't sit correctly at the back, and shows through tighter clothing. Also, if the waistband doesn't sit on the stomach but shifts, that's a sign.
