There are advantages to having your own Block or Sloper based on your body. It helps you make frequent size or fit modifications you always need faster to a store-bought pattern and you can use it to design your own styles.
I've already taught how to draft a block or sloper based on measurements and you can check that out here.
I've also shown how to drape your block on a dress form here.
This time I ordered FOUR custom Blocks from different places and tried each one out. and compared them.
