Is your cup size too small? Find your right bra size after gaining weight

This article contains (Amazon) affiliate links, see my full disclosure at the bottom of the page.

A (slight) change in weight could mean you need another cup size (and perhaps a new band size as well). Three steps that help you find your right cup size again.

My cup size is too small, what size do I need?

It seems simple when you need a bigger cup size. You go up a cup. And this might be just fine.

But when it comes to bra sizing, it is not always this straightforward.

Check out your best cup size, here are my 3 steps


1. Your cup size is too small, your band is fine

Just have a look in the mirror to see if your bra cup is still right for you. Do your breasts need more room?

And your band size is still okay? I mean, the band is supporting you in a firm but comfortable way?

Going up a cup size is what you need. It could mean you would have to go up one or maybe two cup sizes.

2. Your cup size and band size are both too small

If your cups and band are both too small, you definitely want to know your new measurements.

You can still end up with the same cup. How come?

  • changing your band size automatically changes your cup size
  • for example, changing from 44dd to 46dd will mean an increase in cup volume as well

3. Your cup size is right, but your band size isn’t

If your band size is either too loose or too tight you might question your cup size. But having the wrong band might feel the cups are not right, but they may actually be just right!

Changing to the right band size will automatically have an effect on your bra cups. You can only judge your cup size when wearing your right bra band size. It’s not the other way around.

Two examples

  • your bra 44C is too loose, so you change the band to 42. In order to keep the same cup volume you choose 42D
  • your bra 36C is too tight, so you change the band to 38. In order to keep the same cup volume you choose 38B
