From our grand list of the 25 best Halloween costume ideas, Jessie J is certainly one for the charts. The British pop star (and Olympic closing ceremony performer) has been wowing crowds with her voice and her choice of outfits – bodysuits galore. Who knew full bodysuits were still around? You may be picturing those awful 80’s workout videos with neon thong-styled spandex suits but you will certainly win creative points for this one. Plus, it’s easy to throw together. You will just need one crazy-printed bodysuit, shocking lip art, a biker jacket and lace up booties. I would suggest skipping the candy in this number. And the beer.
