Why many women do not wear the right small cup bra size?

I meet a lot of women who wear A and B cups but really need a smaller cup size like AA or AAA. But it could also be they need a B cup instead of the A cup they are wearing. Remember that sizes can be very close.

How come many petites still end up wearing a bad-fitted bra?

  • in the shops, we cannot try the smallest sizes because they don’t sell them
  • we often get the wrong advice after fitting. How can anyone advise you if they do not stock your size and are not aware of the existence of the smallest sizes?
  • 99% of bra size charts do not list the smallest cup sizes. You cannot possibly check your sizes if you’re small, and then likely just will choose a cup size that is closest to your measurements
  • it is very normal to stick to something that is not good for you, like a bad-fitted bra
  • we do not take some time to measure our sizes and check them in the right bra size chart
  • our body has changed and maybe our breasts as well, but we keep on wearing the bra size we’ve always been wearing

It’s very common for small breasted women not to have had the right bra size ever before! If you’re small you tend to avoid the lingerie stores, feeling you don’t belong here.

Why it’s a must for every petite to know their own sizes?

I encourage every woman to learn about her own sizes. Even if you have a bra fitting I always advise to write down your own measurements. It will make it easier to check your size in a size chart (or calculator) and see what your options are. You may have more than one bra size that might fit you fine.

I have 3 different bra sizes and they all fit me fine. I usually have 34AA, but I’m close to the band size 36. In this case, I go for 36AAA. Because when going up or down a band size the cup volume of the bra will change too.

A bra in 34AA and 36AA do not have the same cup volume. However, a bra in 34AA and 32A do have the same cup volume.

The 4 smallest bra sizes

Let me just say ‘there’s no such thing as boobs being too small’.

Women are unique and so are their breasts. That’s why breasts come in all kind of sizes and shapes. Please know that there is a bra size for every petite woman. There is no need to feel left out. Times have changed for the better. If you are a petite breasted woman you can shop too. Thank god some ladies started designing small bras out of their own needs and the needs from women around them. It may seem that boobs only get bigger and bigger. But there are, and always will be, LOTS of women with smaller breasts. 

I personally believe we could fill up a new planet with the whole lot of us. It is my mission for every small breasted woman to become a bra LOVER.

Bra cup A is not the smallest cup size that you can buy. Even though many people may think it is. Other small cup sizes are AAAA cup, AAA cup and AA cup.

I’ve met (and meet) women who wear an A cup bra (or a B cup bra) that is too big for them but never really considered trying a smaller cup size. Although they are not happy with their bras, lacking support and not making their self-esteem grow.
