Fantasy clothing with hoods.
I find most conforming hooded robes end up looking unrealistic because you can't use hair under them (and I'm rubbish at painting on hair). I've only found one hooded outfit so far in my runtime that converts well to dynamic cloth but that one looks great just because I can get a bit of fringe showing beneath it.
I agree with Kalypso's idea about presets for material types too. It would be so handy to have a one-click solution to making an outfit behave like whatever you need from chiffon to velvet.
