Trending Halloween Costume Ideas
Mallory from Beauty in Black (Netflix)
If you want a costume with range, channel Mallory from Beauty in Black. Think sleek, sharp tailoring in black and deep jewel tones, statement heels, and jewelry that says money without saying a word. Slicked back hair or a polished bob, a bold lip, and an unbothered expression pull the whole look together. It is a costume that rewards confidence over props, so if you can serve a little attitude on your way to the candy bowl, this one is for you.
Wednesday Addams
Wednesday Addams is an easy costume with a lot of payoff. Start with a black dress with a white Peter Pan collar (or a plaid pinafore for the Nevermore Academy version), then part hair into two low, tight braids. Skip the smile completely and let a deadpan stare do the talking. Add black tights, black flats or boots, and pale makeup with a hint of dark lip for the finishing touch. It is a low effort, high recognition costume, and the deadpan energy alone will sell it.
Michael Jackson Costume
This was one of the top movies this year and a costume that's guaranteed to be a hit.
Traitors Costume
For a costume with major reality TV energy, go with a Traitors look. Build it around a long velvet or satin cloak in a rich jewel tone like emerald, burgundy, or black, then layer on dramatic gold jewelry and a mysterious, unreadable expression to match. A crown or dark eye makeup adds to the "I might be lying to everyone" effect. It works as a solo costume or as a themed group with friends playing Faithfuls and Traitors, and it is an easy way to turn heads without much sewing or shopping involved.
Couple Halloween Costume Ideas
Harry Potter and the Golden Snitch
For a costume that works solo or as an easy duo, pair a classic Harry Potter look with a Golden Snitch. Round glasses, a lightning bolt drawn on with eyeliner, a Gryffindor scarf, and a robe cover the wizard half in minutes. For the Snitch, go with a shimmery gold bodysuit or dress, gold makeup or body shimmer, and a pair of wire or costume wings attached at the back. It is a playful nod for any Harry Potter fan, and it photographs well if the "Snitch" spends the night just out of reach.
Sinners Movie Costume
For a costume with real style and a story behind it, pull from Sinners. Think 1930s Mississippi Delta glamour: a sharp pinstripe suit, suspenders, and a newsboy cap for a juke joint look, or a slip dress, marcel waves, and bold red lips for a blues club heroine. Lean into the era's texture with worn leather shoes, vintage jewelry, and a guitar or harmonica as a prop if you want to nod to the music at the heart of the film. For a spookier twist, add pale makeup and a hint of fang for the vampire element, turning a period piece look into a full Halloween moment.
