Finding the perfect size: measuring tips and common mistakes
The perfect fit: how to determine your underwear size
Underwear that fits so well you barely notice it. No digging, nothing shifting, just comfort that moves with you all day long – from your first coffee in the morning to relaxing on the couch in the evening. Sounds ideal, right? And that usually starts with one thing: the right size.
However… that perfect size isn't as simple as "I'm always a size M". Because depending on the style, material, and brand, that same size can feel completely different. In this article, we'll show you how it really works. With practical measuring tips, clever insights, and a few things that will likely make you think: "Oh, that's why."
Why your underwear size isn't as simple as a letter or number
Many women assume one fixed size. It's logical, we do that with clothes too. But for both clothing and underwear, your size is not only determined by a letter or number, but also by your body shape and other factors.
The underwear style also influences the ideal size for you. For example, briefs fit differently than hipsters, and biker shorts fit differently again. Add to that differences in materials, and you'll understand why 'your' size sometimes doesn't seem right.
How to measure your size (without hassle)
Accurate measuring is fundamental, but it doesn't have to be complicated. Measure your hip circumference at the widest point of your hips and buttocks. Use a flexible tape measure and make sure it lies straight around your body. It should be snug, but don't pull it too tight.
Want to do it perfectly? Then also measure your waist. That gives a more complete picture of your proportions and helps choose the right fit. Tip: measuring directly on your skin (so not over your clothes) really makes a difference. It saves you from guessing a size.
What do these sizes actually mean?
Once you've measured everything correctly and determined your size based on the measurements, you naturally expect everything to fit well from then on. And yes, with the correct measurements, your chances of making fewer mistakes are significantly higher. But unfortunately, it's not entirely 'fool- proof', and that's because:
- sizes vary by brand
- styles fit differently
- not all fabrics have (equal) stretch
The most important thing to remember: your size is therefore a helpful guideline, but not a fixed fact.
How should the right size feel?
Are you unsure if you're wearing the right size? Don't just pay attention to how it feels when you put it on, but especially to what happens when you move and wear it for a few hours. The right size will remain comfortable, even at the end of a long workday, without you having to adjust it.
The right size:
- doesn't ride up when walking or moving;
- doesn't cut into your skin, even when sitting for a long time;
- stays in place when you change positions;
- doesn't show extra lines under tighter clothing.
Why material affects how a size turns out
Your size determines the foundation, but the material determines how that size ultimately feels and fits. Fabrics with little stretch are less forgiving and can therefore feel tight or restrictive more quickly, even if you are wearing the correct size. Soft, elastic materials, on the other hand, adapt more easily to your body. As a result, the same size often feels more supple and forgiving to wear.
Bamboo, the material from which Bamboo Basics underwear is mostly made, is a good example of this. It is light, supple and moves easily with you. This means that the size not only fits well when you put it on, but also continues to feel comfortable as you move or sit. It also ensures that you don't quickly make a 'bad purchase' if an item is slightly tighter or looser , because bamboo adapts easily.
