Labubus

Without a doubt, the viral toy craze for 2025 is Labubus. From blind boxes to Dubai chocolate, they’re almost on the same level as Beanie Babies from the 90s. Although some people think these furry little creatures are more demonic than darling. Grab your friends and dress as different colors with bunny ears and fuzzy coats.

Wednesday

The gates of Nevermore Academy open once more for the second season of Netflix’s Wednesday. The pessimistic, pigtailed protagonist must solve another mystery while attempting to master her emerging clairvoyant ability. This makes for a great family costume with Morticia, Gomez, Wednesday, Uncle Fester, Grandmama, and Lurch. You can also tack on Enid, Bianca, and Agnes.

Fantastic Four

The impossible has been done: the Fantastic Four finally received a good adaptation. With its star-studded cast and 60s aesthetic, Fantastic Four: First Steps was a super success. These costumes can easily be accomplished with blue turtlenecks and jeans with white accessories (gloves, belts, boots). You can probably find a stencil of their insignia to add with white fabric paint.

Love Island

Summer may be over, but love is still in the air. The seventh season of Love Island USA premiered this past summer, with several spinoffs such as Love Island Games, which will receive a second season this month. You can dress as one of the contestants, or visualize yourself entering the villa! You may want to take a jacket though, since October isn’t necessarily swimsuit season.

Heathers

How very. The 2025 Off-Broadway revival of Heathers brings the cult classic movie back onstage. The “Heathers” wear matching set of blazers and plaid skirts, while Veronica primarily wears blue – at first boho style, then a blue matching set as a Heather.

A Minecraft Movie

Calling all crafters and chicken jockeys for this meme-worthy movie adaptation. With a cast of characters of all ages, A Minecraft Movie will surely be a popular family Halloween costume. Probably since it only takes a blue t-shirt and jeans to be Steve.
