Changing brand after many years with the same one

Short answer: Buy one piece first and wear it for a month. Never replace the whole drawer at once, no matter how good the new one looks. After many years with the same brand, your body knows the fit, and it does not change just because the size has the same name.

Why you should try first

After many years with the same brand, your body knows the exact fit. A new brand can have the same size on paper and still sit quite differently at the waistband, the crotch and the leg opening. You only find out after a full day, so a single piece is a cheap way to get the answer.

What to measure

Measure chest, hips and length on the garment you like, and write the numbers down. Compare them with the new brand's size chart in centimetres, not with the letter. That way you find the size closest to what you already know. Look at bamboo underwear for men and compare the figures.

Why brands differ

Every brand has its own pattern and its own scale, and there is no shared standard. That is why a medium from two brands can be several centimetres apart. Fabric weight and elastane share also change how a garment sits. These are only differences you can allow for once you know what you are looking for.

Do not replace the whole drawer

Even if the new brand looks good, do not change everything at once. If you buy ten pieces and find the fit is not yours, you have ten pieces sitting unused. If you buy one, you have lost very little and can try another size or another brand.

How to test

Wear the piece on an ordinary day with desk work, walks and a couple of hours of movement. Notice whether the waistband rolls, whether the legs ride up and whether the seams chafe. Then wash it a few times and see if the shape holds. A month of normal use gives an honest picture.

What to notice

Pay attention to the small things: whether the waistband tightens after a few hours, whether the fabric feels warm or cool, and whether you can feel the seams under your clothes. If you think about it during the day, it is rarely the right piece. Good underwear is the kind you forget you are wearing.

When switching makes sense

Switching makes sense when your old brand has changed its cut, when the range has been discontinued, or when you would like a different fabric. Then it is a concrete need, not a whim, that drives the choice. Look at JBS of Denmark and Bamboo Basics for options that can be compared.

When the range is discontinued

If your regular piece is discontinued, you can buy a few extra while they still exist and use the time to find a replacement. Look for the same weight, the same type of seam and measurements close to your own. That way you switch at your own pace and not because the shelf is empty.

Use both brands

You do not have to choose completely. Many people use one brand for everyday wear and another for training or for days when they want a closer fit. You get the benefit of both and do not depend on one brand always having your size. Write down the size for each brand.

Frequently asked questions

How long should you test?

A month of normal use and a few washes. Then you have seen how the piece fits, feels and holds its shape in your own everyday life, not only in the fitting room.

What if it does not fit?

Then you know after one piece instead of ten. Try another size or another brand before you buy more.

Can you use two brands at once?

Yes. Many people use one for everyday wear and another for training. Write down the size for each brand so you do not have to guess every time.
