Bamboo bh first purchase and what to measure
Oct 10, 2026
Short answer: Your first soft bra should fit close without pressing, and for that you need two measurements: around the ribcage under the bust and around the fullest part above it. A bamboo bh in viscose from bamboo is soft on the skin, but the right size decides whether it feels good.
Why a soft bamboo bh is a good place to start
A bra in soft fabric often has no wire and few seams, so it rubs less and is easier to get used to. Viscose from bamboo is smooth against the skin and gives a little. Many people choose a bamboo bh as a first bra because it is easy to live with every day.
How to measure under the bust
Stand relaxed with your arms down and place a soft tape measure horizontally around the ribcage just under the bust. The tape should lie close but not press. Write the measurement down in centimetres. It is your base measurement and shows which band width suits you.
How to measure over the fullest part
Then measure around the fullest part of the bust, again with the tape horizontal and relaxed. The difference between the two measurements shows how much room the cups need. Measure twice if you can, and without thick clothing, so you get an honest number.
Compare with the size guide
Use your two measurements and compare with the size guide on the product page instead of going by a size you know from another brand. Brands cut differently. You will find the styles in our category bamboo bra, where each style has its own guide.
Check the fit once it is on
The band should lie horizontally around the body and not ride up at the back. The cups should cover the bust without making edges or empty areas. The straps should sit on the shoulders without cutting in. Lift your arms and move about so you can feel whether it stays in place.
What to do if the size does not fit
If the band is too loose, or the cups form folds, try a smaller size. If the band presses, or the bust spills over the edge, try a larger one. Adjusting once or twice is normal. The fit also changes with time, so measure again after a while.
Caring for your first bra
Wash the bra gently as the label says, preferably in a wash bag, and dry it flat or on a hanger. Avoid high heat and the tumble dryer, which can pull the fabric out of shape. Rotate between two or three so each has time to rest and keep its fit.
The rest of the first layer
Once the bra fits well, you can add bamboo underwear for women in the same fabric and a soft bamboo top for women over it. Then the first layer feels the same and you do not have to adjust anything through the day.
Frequently asked questions
How do I know my bra is the right size?
The band lies horizontally and close without pressing, the cups cover the bust without folds, and the straps do not cut in. If you can lift your arms without the bra shifting, that is a good sign.
How often should I measure myself?
Measure when you buy a new bra, and again if the fit changes. The body changes over time, so a new measurement can give a better fit.
How often should a bra be washed?
It depends on use. A bra close to the skin is often washed after sweat, and it helps to alternate with a second one so each gets time to rest.
