Gaston in “Beauty and the Beast” is the quintessential male chauvinist. Portrayed as self-centered and arrogant, the character pursues the female protagonist, Belle, relentlessly. His egoistical nature is obvious from the way he treats his loyal sidekick, LeFou. This ego is what eventually turns him into a vengeful and despicable villain once he learns that Belle was in love with the Beast and not with him.
Gaston is portrayed in the 1991 animated movie as wearing a red shirt with a yellow collar and a pair of black trousers. He sometimes wears a more formal outfit with a red coat and a brown waist coat. This changed in the 2017 live action movie, in which he has a more polished look and wears the red coat more regularly. In some scenes, he wears a brown coat with red collar instead.
He also wears brown trousers instead of black. Despite the change, the use of red in his outfits has remained consistent. So it’s important to remember this when assembling a DIY Gaston costume. There are also some changes in the weapons he uses in the live action movie.
While Gaston’s favorite weapon in the animated movie is a bow and arrow, the live action movie portrays him with a sword and a pistol.
