I don't know how to describe it perfectly, but I'll do my best. A lot of character designs have fluffy fabric, like scarves that don't lay flat or pants that puff out at the bottom.
For example, though I'm looking for a general answer, I'm trying to figure out how to make Sheik's scarf/muffler
. It would be simple enough to just take white fabric and throw it around, but it wouldn't get those lovely folds and flops I'm looking for.
