10 M3GAN Costume Ideas to Slay (and Serve Dance Moves) In This Halloween

Just as killer as M3GAN’s dance moves is her style, and tbh, we can’t think of a better costume idea for Halloween 2023. The murderous robot stole scene after scene in arguably one of the most iconic horror films of our generation, dressed in a prep aesthetic complete with a tailored a-line dress, bowtie, and ballet flats. The engineering behind the lifelike doll might be complex (she can talk, listen, watch, learn and, well, kill all who cross her bestie Cady, after all) but the science behind her wardrobe is actually pretty straightforward.

Think about it: Most of M3GAN’s outfit probably already exists in your closet. Layer a beige dress over a striped long-sleeve tee and pair of white tights, slip on black Mary Jane ballet flats, and accessorize with a blue striped kerchief. Voila, you’re done. You can even elevate the look with one of M3GAN’s outerwear pieces, such as her brown satin trench (don’t forget the oversized sunnies!) or black double-breasted peplum coat. Halloween nights can bring a chill, especially if you’re out trick-or-treating.

Halloween 2023 may be a few months away, but why wait? Prepare for the “slay date” with one of these M3GAN costume ideas. Trust us, they’re killer.

M3GAN Costume Set

For a complete M3GAN costume ensemble, look no further than this option from WalMart. All you need is a long blonde wig with soft curls to finish off the look.

Double Breasted Sleeveless Dress

This beige a-line dress is a great dupe for M3GAN’s signature outfit — and thanks to its classic cut, it’ll remain a wardrobe staple long after Halloween passes.

Striped Long Sleeve Tee

You can’t forget to layer with this gray-and-white long-sleeve striped tee. Perfect for M3GAN, perfect for cool fall nights.

Women's Opaque Tight

Another essential layering piece: white tights. To recreate M3GAN’s look as accurately as possible, you want an opaque pair just like this.

Emjane Mary Jane Ballet Flat

Who is M3GAN without her black ballet flats? The reliable shoe lets her walk, run, dance... and crawl... through any and every ordeal. Plus, ballet flats are making a comeback (and we have a feeling the killer robot doll has a lot to do with that).

Silk Square Scarf

The costume simply isn’t complete without M3GAN’s blue-and-red striped kerchief. Just tie it in a bow around your collar and ta-da, you’re ready to go.

Women's Double Breasted Long Trench Coat

While this isn’t as silky and luxurious as M3GAN’s satin trench, this option from Amazon is the right color and cut for your costume recreation.

Round Oversized Sunglasses

Whatever you do, don’t forget the round oversized sunnies.

Faux-Fur Double-Breasted Wool Trench Coat

For those in super cold climates on Halloween night, you can’t go wrong with M3GAN’s black peplum coat. This pick even comes with the faux-fur lined lapel and double-breasted tailoring.

Tights with Control Top

Pair M3GAN’s black statement trench with a pair of opaque black tights and Mary Jane ballet flats, and you’ve just achieved one of the easiest Halloween costumes out there.
