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.

The band digs into your skin and leaves skin marks long after taking off your bra.

  • the bra band should give you firm support
  • it’s okay 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


Do bra bands stretch out?

Bra bands do stretch out. It’s what the elastane in your bra does.

In time your bra will gradually lose its elasticity.

  • wear your new bra on the first hook (leave the other hooks for later)
  • you’ll notice in time the bra becomes less and less stretchy.
  • use the second and third hooks to still have enough support coming from the fabric.

Using a bra extender can be a good solution for bras that are too tight on you.

Did you know a change in your band size has a direct effect on the cup volume?

Going down or up a band size will automatically change your cup volume.

Let me explain this with 3 examples.


Example 1. The bra band is too small & cup is fine

A woman wears 90D and needs a bigger band. Her cup size is fine.
Her possible new size is 95C.


Example 2. The bra band is too small & cup is too big

A woman wears 90D and needs a bigger band and a smaller cup.
Her possible new size is 95C or 95B.


Example 3. The bra band is too small & cup is too small

A woman wears 90D and needs a bigger band and a bigger cup.
Her possible new size is 95D or 95DD.

Knowing your sizes will make you understand what bra sizes to try. It can well be you’re in between two sizes and you could try (and fit!) different sizes.
