Bust adjustment

If the pattern should be drafted with a basic full bust adjustment (FBA). This will result in a more fitted garment for people with breasts.

If you don’t enable this option, Tina will essentially be drafted for a body without breasts that has the same chest circumference as your body with breasts. For people with breasts, this will cause a bunch of extra fabric at the chest and armholes that will make the top look like a poor fit.

There is usually no need to disable this option. It will have little effect on people with smaller busts or no breasts.
