What bra size should I wear?

If you speak Polish simply visit

To know what bra size is good for you, you must first know, what the bra is for. Your breast is build inside of connective tissue and fat, covered with the skin. It has no muscle inside (although there are some muscles around, that support it in a way). The skin is stretchy, the heavier the content is, the more pressure is put onto the skin and so it gets misshaped. On the other hand, then it is squeezed, the content gets misplaced: it goes to the back and under your arms, creating weird shapes. The first problem is more visible when you have bigger bust, the second one, when you have it smaller.

The main task of a bra is to support your bust and keep it in its place.

Have you ever hiked with your rucksack? Have you ever used the hip band? Do you remember how your arms hurt when you did not use it? It shows you a universal rule: it is better to put the load on band and strap. The same rule can be applied to bras. Actually, the bra band should support 90% of the weight, the straps getting only 10% of it. How to achieve it? Well, the band has to be tight enough and the cups should be large enough.

What does a bra size mean? The first number (band) is the length of the band when it is laying on the table, i.e. not stretched. The letter (cup) means the difference between the band and the size in bust (yes, the size of a bra and the size of a person). Some (13) cm difference means A and then any additional 2cm make a cup one letter bigger. (There is a lot of confusion about the bra sizes. The one I’m using in my blog is so called “EU size” – it’s the one you have to use when buying bras in Swiss shops. Other popular metric is “UK size”, which is calculated in inches and sometimes uses two letters – I will explain it later).

You don’t have to calculate the size by hand. Visit this page: Scroll down to the very bottom. You’ll find the bra-size calculator there. Put into the first field the girth (your size) below the bust, measured very tightly, without the air in your lungs (breathing out). Put into the second field your girth in the bust, measured loosely without a bra (or in a soft bra – and take the bigger result). Press “Przelicz” (Calculate). You’ll get some results: the first is the UK size (very useful for online shopping), the second and third results are the alternative ones, to be used if a particular model is too loose/too tight. The last one is EU size – the one you may try to use in Swiss stationary shops.
