Halsey
A few selected A-listers got two entries on this list simply because their costumes are just too good not to include. This time, Halsey dressed up as the Corpse Bride, you know, the one from the Tim Burton fantasy film, Corpse Bride. Choosing a skeleton-like cartoon creature for a costume is risky, because it means you have to put a lot of effort in order to perfect the makeup.
The skeleton makeup has to be flawless – the whole costume rides on that. And Halsey certainly brought her A-game, probably with the help of a skilled team of makeup artists. Once again, we have to wonder how many layers of makeup she has, and how many hours it took perfecting the look (and how long it would take to wash it all off). Either way, it was worth it, because the result is stunning.
