How to measure bra size

Step 1   Measure your band size

Measure your band size
  • put the tape measure around your underbust
  • write down the inches or centimeters

Step 2   Measure your cup size

Measure your cup size
  • put the measuring tape around the fullest part of your breasts
  • don’t pull too tight
  • write down the inches or centimeters

You’d rather go for a bra fitting? That’s fine. My advice is to write down the measurements after your fitting. Knowing your sizes will give you more control when shopping for a bra. You might be just in between two different bra sizes. Also depending on the bra style and brand you might wanna to try them both.


How often does our bra size change?

Our body is unique, so is our bra size

A woman’s body may change during life through several causes. If your body changes, it will often change the size or form of your breasts.

We can all think of reasons why our body, and therefore our breasts, can change. Like, the weight that you gain, the weight that you lose, hormonal changes, medication, pregnancy, nursing a child, surgery to one or two breasts, aging. Read the full post on causes of our breasts to change size »


Washing bras by hand, why should you?

The washing machine and bras don’t mix that well

Likely you are or have been, tempted to use the washing machine once in a while (I did). Instead of what lingerie experts will advise us on this.


Bra sister sizes do I have one?

You too might fit different bra sizes
  • Most women can wear different bra sizes and they all fit them well. So that’s different sizes for the same woman!
  • Going up or down a band size changes your cup volume as well. For example, the bras 40C and 38D have the same cup volume. Read more about bra sister sizing »


How to determine your best bra band size?

Looking for your bra size? Always start with your bra band size first

There are about 14 different band sizes available. Although not every brand has the whole range of band sizes 28 – 54.

The smaller the band size you need, the smaller your underbust is. How do you measure your bra band size? And how tight should the band be?

You could be just in between two band sizes. What to choose then? How to determine your best bra band size? »


Bra band size too small?

A change of band size will change the cup volume

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.

Women who need cup AA or AAA won’t find their bra size in most size charts. Are you petite? Always check a size chart that includes all small cup sizes.

Shouldn’t I go to a lingerie store instead?

Of course, you can go to a lingerie store to have your measurements taken. My advice is to write down the measurements so you’ll be able to look at it again.

Most women have to measure their sizes many times in their life. Our bodies may change in our lifetimes.

I became a bra lover only after I learned about my own measurements and finding my bra size in a proper size chart. Not only did I find my best bra size myself, but I also found out that I can wear different bra sizes depending on the bra style and brand I choose.
