This process consists in adding sizes around the pattern pieces. This is recommended for upgrading maximum two sizes ( I sometimes do more…), and is usable for multisize patterns where the classic one works for more, and is usable for any pattern.
Warning 1! In this post, I am making major changes : not a good thing if you refer to what is written in books. I just think that this one is easier.
Warning 2! With this method, the fit won’t be as good as with patterns that you buy at your size, but if you want that gorgeous Vogue pattern that stops at size 20, you have to try anyway…
This post has 7 main paragraphs. They have theoretical parts and examples parts. Some of the paragraphs are skippable, but I tried to be as complete as I could.

1) The pattern
I am using a basic bust pattern. It is an easy one to use for the upgrading purposes. It has a single dart.
2) Differences between sizes
|size of the||48||14||8||4||0||4||8||14||20|
This table shows how many centimeters there is between sizes. I am so sorry for not using inches in this one, as in Europe, we rarely use them, and most of the patterns in Vogue also do the metric system. The main reason is also that talking about inches confuses me… And you do not want me to be confused…
For example, if you are a size 50, and your pattern stops at a 42, there is, on average, a difference of 20 centimeters between them at every measurement.
