Wie das 3-Size-System deinen Kleiderschrank revolutioniert
Updated: Published:

Size S, M, or L? If you've ever faced a size chart while buying underwear and still got it wrong, you know the problem. Finding the perfect fit is a gamble with most brands.

With its 3-Size-System©, Buttz puts an end to this – covering everything between XS and 5XL with just three sizes.

Why the Standard Sizing System Fails

Most underwear brands work with nine or more sizes – and still nothing fits right. No two bodies are identical, and size charts vary from brand to brand. If you wear an M with one brand, you might be an L with the next. The result: guesswork, mispurchases, returns.

Moreover, the body constantly changes – due to the cycle, sports, pregnancy, or simply life. Underwear that fits today might be too tight tomorrow.

The 3-Size-System©: Three Sizes That Really Work

The Buttz 3-Size-System© is based on a simple principle: the material is so elastic that one size covers a broad range of body types – without cutting in, without slipping.

  • Size 1: XS–M
  • Size 2: L–2XL
  • Size 3: 3XL–5XL

No more guesswork. No more size roulette. Just three clear options.

What the Material Makes Possible

The High Elastics are made from 80% nylon and 20% elastane – a material mix that combines extreme stretchability with shape retention. This means: the underwear stretches with every body but always returns to its shape. No stretching out, no marks.

Plus, seamless construction: no edges, no tags, no visible lines under clothing.

What Specifically Changes

Fewer sizes mean less uncertainty when buying. Fewer mispurchases. Fewer returns. And underwear you won't bury in a drawer after a day because it cuts in.

The 3-Size-System© is not a marketing promise – it's the reason why High Elastics are Buttz's best-selling item. See for yourself: All Panties at a Glance.

FAQ

How does Buttz's 3-Size-System© work?

Instead of many rigid sizes, Buttz only has three: Size 1 (XS–M), Size 2 (L–2XL), and Size 3 (3XL–5XL). The extremely elastic material adapts to every body within these ranges – without cutting in or slipping.

What do I do if I'm between two sizes?

The 3-Size-System© is made precisely for this. If, for example, you are between M and L, this falls into the transition area between Size 1 and 2. In this case, we recommend Size 2 – the material gives way and adapts.

Does the 3-Size-System© apply to all Buttz products?

The 3-Size-System© applies to all High Elastics products. The Period Keeper and the Tangster have their own sizing, which is indicated on the respective product page.
