Why the same size does not fit across brands

Short answer: There is no common standard for clothing sizes. Each brand decides for itself how many centimetres a size covers, so the same letter can feel completely different.

No official standard

Letter sizes are not regulated. Two brands can use the same letter for measurements that are several centimetres apart.

The cut matters just as much

A close-fitting model and a loose model can share the same measurements and still feel entirely different on the body.

The material plays a part

A fabric with stretch forgives more than a firm one. Bamboo viscose stretches, so a close-fitting model often feels more comfortable than the numbers suggest.

What to do

Measure yourself once, write the numbers down, and use the chart of the brand every time. See the measuring guide.

Find the charts

The charts are gathered by brand, for example size guide Bamboo Basics women and size guide Resteröds.

If in doubt

Choose according to how the piece is to be used. See between two sizes and the size guide.

When you buy several identical pieces

If you buy several pieces of the same model, be sure of the size first. One piece as a test costs less than a whole pack you do not use. See bamboo underwear for women.
