The band on your bra rides up at the back

Short answer: Short answer: The band rides up because it is too loose, not because the straps are too long. Tighten the band, loosen the straps and measure yourself again.

The band carries the weight

Most of the support comes from the band around the body, not from the straps. If the band is too loose, it travels up toward the narrowest part of the ribcage, and the straps end up carrying everything. Then you tighten the straps, and the band rides even further up the back during the day.

How to check the band

The band should sit level all the way round and be snug enough that you can just fit two fingers underneath. Raise your arms above your head in front of a mirror. If the band follows your arms up toward your shoulders, it is too big, and you need a smaller band or a bigger cup.

Try the sister size

Go down one band size and you need one cup size up to keep the same volume. Many people suddenly find a much better fit this way, without really changing the cup size. See bamboo bra without underwire, where several models have wide hooks and a soft band.

When the bra is worn out

The elastic in the band gives way over time, even when the cup still looks fine. If you are always on the tightest hook and the band still rides up, that is a sign the bra needs replacing. Replace it instead of tightening the straps as a temporary fix that will not hold.

Washing wears out the elastic fastest

Hot washing and tumble drying break down the elastic faster than the rest of the fabric. Wash the bra at thirty degrees in a wash bag and let it air dry flat. That way the band keeps its stretch longer, so you avoid switching to a new model just because the elastic gave out too early.

Straps should only guide

The straps should keep the cup in place and guide the direction, not carry the weight of the bust. If you can slide a finger easily under the strap without it pulling, the fit is right. Tighten them instead of the band and you end up with sore shoulders and a top that still rides up.

Hooks give room to adjust

Always buy a bra that fits on the loosest hook, so you have room to tighten the band as the elastic wears down over time. If it only fits snugly on the outermost hook from the start, there is no reserve left, and you will need to replace it far sooner than necessary.

Choose the model for your body shape

Some body shapes need a wider band and extra rows of hooks to spread the pressure evenly. See bamboo sports bra, where the wide elastic band stays put during movement. A sports bra also works well for everyday wear if regular models keep riding up your back.

Good habits in everyday use

Always put the bra on by hooking it at the back and turning it around, not by pulling it on from the front. That way the band sits straight from the start instead of crooked. See the full range under bamboo underwear for women if you want to compare bands and hooks across models.
