The 5 Products You Need to Transform Into M3GAN For Halloween

What to Wear: The doll's final look, while ominous, might make for the most stylish M3GAN Halloween costume of all. To re-create M3GAN's take on the peplum trend, grab a black peplum trench coat ($27, originally $33) — if you can find one with a faux fur collar, even better — or a peplum blazer ($42, originally $45) and a pleated skirt. Slip on a pair of black tights ($21, originally $42), black gloves ($12), and Mary Janes ($40) to tie the monochromatic costume together. It might not be her brightest or cheeriest ensemble, but it's certainly fitting for a chilling M3GAN Halloween costume.
