Currently when you are disguised with a helmet/poncho/hoodie et cetera, your description is reset so that people can't meta your identity by reading it. This is all good but there are also other things that could be done to dissuade this from an OOC perspective, because even if we're all good players who try to be ICly reasonable and think how that average man wearing a blue shroud might be just one in a million, sometimes we can't help but realize that they are the only one with "queer" shortdesc.
So my suggestion is to reset your @shortdesc to "male" or "female" (instead of man and woman to account for child characters and whatnot) automatically and temporally while you are wearing the disguise.
