Gorilla Suit Day 2025 – January 31, 2025

We love a day that lets us unleash our inner primate, even if it is in a suit(!) — and that’s why we are very excited about Gorilla Suit Day, which comes around on January 31 each year. This King Kong-sized day is meant to honor the monkey suits that are worn on Halloween, at costume parties, movies, and sometimes just for fun. So don your gorilla suit and join us for the celebrations.

History of Gorilla Suit Day

The very first suit was handmade in the 1920s by Carlos Cruz Gemora, a Hollywood make-up artist. His study of real gorillas from the San Diego Zoo coupled with his make-up expertise gave his suit authenticity.Before Gemora’s gorilla suit, movies had a version, which was unfortunately not very close to the real thing. This was because Westerners had not laid eyes on this primate until the 1860s, and even then, this animal was something of a curiosity back in the early 20th century. This made the initial gorilla suits somewhat questionable representations of the real animal.By the time Gemora’s realistic suit came around, the movie industry — and gorillas — were enjoying a lot of popularity. This went on for the next few decades, until the 1950s, when their scare factor went down.An innovation came into existence — special effects. It turned the film world on its head. No longer were men in costumes required; computers could take care of it all. A few followers of the good old times — Rick Baker, for instance — kept the gorilla suit alive. Baker kept away from special effects and illusions, using the gorilla suit instead to appear in movies like “Schlock,” and “The Thing With Two Heads.”In 1963, one of “MAD” magazine’s ‘Maddest Artists’, Don Martin, wrote a 56-page comic about a character mocking the then-fictitious Gorilla Suit holiday. This character is then assaulted by gorillas and people in gorilla suits, in trademark “MAD” magazine’s absurdly hilarious style. This paperback was called “Don Martin Bounces Back,” and although the book itself is out of print, the holiday lives on through Don Martin fans. They get together with fans of “MAD” magazine to celebrate this unofficial holiday in memory of the artist and the suits themselves.

Gorilla Suit Day Activities

  1. Wear a gorilla suit
