Bra band size too small

You probably know the feeling of a bra band feeling too tight. However, most support from a bra comes from its band. So a firm band is what you should look for, but definitely not too tight.

  • Do bra bands stretch out?

How do I know if my bra band is too small?

A bra band is surely too small if you feel your band the whole day. Are you feeling that relieved taking your bra off in the evening? This is not a good sign.

This is how a bra band should feel like:

  • the bra band should give you a firm support
  • it’s ok to feel the bra band being a bit tight when wearing it for the first 20 minutes
  • the elastic fiber will adjust to the warmth of your body and relaxes a bit

Do bra bands stretch out?

Bra bands do stretch out. It’s what the elastane in your bra does. It is made to be stretchy and therefore does the job for your underbust and breasts.

Always wear a new bra on the first hook. You’ll notice in time the bra becomes less and less stretchy. You then use the second and third hook to still have enough support coming from the fabric.

Using a bra extender can be a good solution for the bra you bought and is still too small after all. Or you might have gained some weight and use extenders so you can still wear your bras (that is if your cup size is still alright).

Do bra cup sizes change based on band size?

Going up or down a band size will change the size of your cups

Did you know a change in your band size has a direct effect on your cup size? Going down or up a band size will automatically change your cup volume.

What you should realize is the fact that going up a band size will change your cup volume as well. For example, a bra in 32C has a different cup volume as a bra in 30C.

Let me explain this with a few examples.


Going up a band size and keeping the same cup volume

  • I wear 90D and I need a bigger bra band – I want the same cup size.
  • Try 95C.

By going up a band size the cup size will automatically be larger. So you would have to go down a cup


Going up a band size and needing a different cup size as well

  • I wear 90D and I need a wider bra band – and a smaller cup size
  • Try 95C or 95B. By going up a band size the cup size will automatically be larger.
  • I wear 90D and I need a wider bra band – and a larger cup size
  • Try 95D or maybe 95DD.

Knowing your sizes will make you understand what bra size to try. It can well be you’re in between two sizes and you could try (and fit!) different sizes. Read more about Bra sister sizes | do I have one?
