One of the horror genre's most sinister motifs, the haunted doll, received a 2023 upgrade in Universal Pictures's "M3GAN." At first glance, the doll resembles an unsettling version of a human child, but the lifelike android, programmed to "protect" her paired human to terrifying extremes, isn't your typical American Girl doll. She walks, talks, and wields a two-foot knife while rocking to the beat of her own twisted murder ritual — a habit that inspired one of TikTok's biggest dance trends earlier this year. Between being absolutely terrifying and surprisingly stylish, a M3GAN costume sounds like the perfect way to stir up some fun this Halloween.

Besides the fact that she seems to be powered by vengeance and malice instead of batteries, M3GAN does share a few traits with your typical doll. Namely, the AI robot has a rotating collection of outfits made for a stroll through the park, a four-legged chase through the woods, or a premeditated escapade into the neighbor's basement. From her preppy peplum coat to her blood-spattered khaki dress, M3GAN's immaculate looks are part of what makes her the creepy robot we love to hate.

While many of the pieces from her outfits are custom, that hasn't stopped hundreds of horror lovers from showing the villainous robot some sartorial love on social media with their own M3GAN costumes. With Halloween almost here, many TikTok users have shared plans for their M3GAN-inspired Halloween costumes, complete with wavy blond wigs and patent-leather Mary Janes, and we've been all ears.

To help you replicate the rogue AI doll's signature style, we rounded up a few of our favorite M3GAN costume ideas and the exact products you'll need to recreate them. From her classic babydoll dress to the more elegant pieces in her wardrobe, each of these M3GAN costumes will leave your friends, family, and neighbors stunned at the next Halloween party. Ahead, see how to dress like the horror-movie villain and check out some of our favorite M3GAN Halloween costumes.

M3GAN Costume: Classic Khaki Dress and Mary Jane Shoes

What to Wear: For a M3GAN costume that emulates her classic look, layer a khaki dress ($41) over a striped blue shirt ($17). If you're going for authenticity, make sure the dress has pleats along the skirt and add blue stitching along the hem, sleeves, and collar.

Tie the creepy ensemble together with white opaque leggings ($13-$15), black Mary Janes ($44), a tricolor ribbon, and a fake sword. Also, if you don't have wavy golden hair, complete your M3GAN Halloween costume by adding on a medium-length blond wig ($21) (bonus points if it has a middle part).

What to Wear: Similar to her signature look, M3GAN's second ensemble is her original outfit layered underneath a brown satin coat ($18, originally $85) and paired with round sunglasses ($12). For a scarier version of this M3GAN Halloween costume, muss up the wig and splatter some fake blood on your clothes.

M3GAN Costume: Black Peplum Coat

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.
