How should I go about making a long trench coat?

So i'm modeling a lady in a long trench coat (who's gonna be animated ofc) and im unsure of how to make the coat itself. should i add bones to the coat or use a fabric simulator for it? the style of the short isn't realistic, more like semi realistic? but the character will be dancing and i want the coat to more accurately. thank you! (I use blender :) )
