Brief Sizes – A Guide to the Right Fit

Short answer: You find the right brief size by measuring your waist and hips and comparing them with the brand's size chart. A brief in the correct size sits close without squeezing, does not cut into the skin and does not ride up. If you are between two sizes, choose the larger one.

How to measure yourself

Measure your waist at its narrowest point and your hips at their widest point with a soft tape measure. Write the numbers down and hold them up against the size chart for the brand you are buying. The basic principles are set out in the guide to finding the right size in bamboo clothing.

Sizes vary between brands

A medium is not the same at every brand, so use the charts rather than guessing. See for example the size guide for JBS of Denmark women, the size guide for Boody women and the size guide for Bamboo Basics women.

How the brief should sit

The elastic should lie flat against the skin without leaving deep marks, the leg edges must not cut into your bottom, and the brief should stay in place when you move. If it squeezes or rides up, the size or the style is wrong. Find the right shape in the range of bamboo briefs.

Frequently asked questions

How do I find my brief size?

Measure your waist and hips and compare them with the size chart for the specific brand. The charts vary, so measure rather than guess.

Should I choose a bigger size if I am in doubt?

Yes. A slightly large brief in stretchy bamboo viscose still sits well, while one that is too small squeezes and rides up.

Why do my briefs cut into my skin?

That is typically a sign that the size is too small, or that the elastic in that style is too tight for your body shape.
