Why the bra band rides up at the back

Short answer: The band rides up because it is too loose. The weight pulls from the front and downwards, and a loose band gives way and slides upwards at the back. It is almost never the straps that are the problem.

A loose band is the main cause

A band that does not sit firmly is pulled upwards by the weight at the front. The answer is a size down in the back, not tighter straps. See bamboo bra without underwire.

The straps make it worse

If you tighten the straps to compensate, the band is pulled even further up. That is the most common mistake.

Go down in band and up in cup

If you go a size down in the back, you have to go one up in the cup to keep the volume. See size guide for full bust.

The elastic may be used up

A bra that fitted well for two years may have lost its stretch. Elastic is broken down by heat. See washing and care.

Test on the outermost hooks

A new bra should fit on the outermost set of hooks, so you can tighten as the elastic gives way. See bamboo underwear for women.
