S, M, L and XL in underwear, finding your place on the scale
Oct 10, 2026
Short answer: When you choose bamboo briefs for women, the letter on the label is only a guide, not an answer. Measure yourself, read the size chart and choose by your own measurements rather than by the size you usually take. Here is a simple way to find your place on the scale.
Why S, M, L and XL are not the same everywhere
The letters follow no shared standard, so an M from one brand can fit like an L from another. That is why many people buy the wrong size even when they know theirs. Never take the letter for granted when you shop for bamboo briefs for women.
Measure yourself before you order
Use a tape measure around the widest part of your hips, and ideally around your waist as well. Stand relaxed and let the tape lie flat without pulling it tight. Write the numbers down so you can hold them up against the chart for bamboo underwear for women.
How to use the size chart
Find your hip measurement in the chart and see which size it points to. If you fall between two sizes, think about whether you prefer a close fit or a loose one. The chart is a better starting point than your experience with other brands.
Between two sizes, what to choose
If you fall between two sizes, pick the larger one when you want the underwear to be barely noticeable. Pick the smaller one if you want it to stay firmly in place. The fabric stretches, but a size that is too small can still cut into the skin.
Bamboo briefs for women and the stretch of the fabric
The fabric usually contains some elastane, so it stretches and returns to shape. That makes the choice of size more forgiving, but not unlimited. If you often have to pull at the waistband, the size is probably too small.
When your body changes
Weight, pregnancy, age and periods of swelling can change your size without you doing anything wrong. Measure again each time you order and go by today's numbers. That is more reliable than the size you wore last.
The same size in the rest of the wardrobe
Your underwear size is not necessarily the same as your top or sock size. Check each category on its own, for example in the chart for bamboo T-shirts for women. Bamboo socks usually come in size ranges rather than a single letter, so read those separately.
How to check the fit once the parcel is home
Try the underwear on and move around a little: sit, bend and take a short walk. The waistband should lie flat, and the leg openings should neither press nor roll. If it does not fit, swap for another size rather than getting used to it.
Frequently asked questions
Should I size up in bamboo underwear?
It depends on your measurements and the size chart, not on a fixed rule. The fabric stretches, but if you are clearly between two sizes the larger one can be more comfortable when you do not want to feel the underwear.
How do I measure my hips correctly?
Stand relaxed with your feet together and lay the tape flat around the widest part of your hips. Do not pull it tight. Write the number down and compare it with the chart on the product page.
Can the size change after washing?
Follow the care instructions on the label. If you do, the underwear should keep its fit. Washing or drying at too high a temperature can affect the fabric, so avoid it when the symbols say no.
