Lady Gaga is the queen of the costume, constantly reinventing her image and our notion of what makes for an acceptable ensemble. Like Perry and Cyrus, there’s a lot to choose from here, but Gaga’s outfits are undoubtedly the strangest. At times, they’re all skin with a little lace or latex, and at other moments, they’re so covered that they’re borderline chaste. While all of Gaga’s looks make for fun dressing up, this one is perfect for Halloween in its eeriness. Completely envelop a dress and headband with pale yellow ribbons and make sure you have the hair color to match. Cake all your remaining skin in white powder, the better to make your bright-red lips and blush pop, and voilà! Crucial to this look is the ghostly demeanor: stay in character, making sure not to smile – and if anyone asks what you are, say you’re a monster.
