Are you giving Stephanie the same warning? I have quite a few unpleasant memories with quite a few of her 'besties' who wear capes and yet you are telling me not to dress as someone I care for and admire, because it might 'stir up memories'.
Hell, someone could come dressed as Batman, an image that causes a severe visceral reaction in me and yet that is their choice, because it's just a costume, and just a party.
But no, of course not, it's just me who gets told her costume isn't good enough. Makes perfect fucking sense.
