No matter how you arrive at the final version of a fitting muslin, and no matter how you eventually plan to use it, the moment of truth is always the same: trying on the muslin and making the appropriate adjustments to fully customize it to a live body.

As you’ll see as you work on the muslin, sometimes you can deal with these issues separately, and sometimes you have to solve them at the same time. Suzanne Stern shares the tools you’ll need to fit a muslin successfully.
