Regarding this:
> It would also be nice if smaller elements like the collar or waist band could be made of an alternate fabric type without affecting the dress stats.
It actually looks at the size of the piece you use the fabric on. In other words, if you use a different fabric for a small element of the dress, the effect on the score will be negligible.
