What Is Size Four In Centimetres?

It doesn't actually work in centimetres, because different manufacturers interpret clothing sizes differently - and also people are usually bigger in one part of their body than another. You'll probably have noticed how you can try on two different garments, both with the same size on the label, and one is too big and the other is too small! You can only get centimetre sizes with things that are measured in one area, like bra sizes and trouser leg lengths. If you are buying online or from a catalogue, though, it should be possible to get exact measurements for a garment from the company selling it.

I have found a very useful women's clothing conversion chart which compares, European, US, UK, Japanese and other sizes. It can't give you the information you asked for, but it is very handy.
