Basic Block
First things first. Before starting making new clothes, I should alter my basic block a bit as it’s been 8 years since I made it. Luckily the sizes aren’t that differnt and actually the old one still fits me well.
When you draw a flat pattern, what block you use is very important. Having said that, I never altered it before even when I gained or lost weight… It is a bit annoying yet necessary process to make well fitted clothes, in my opinion.
