The 'Fav Princess Peach Filter' meme is a viral trend that took over social media platforms like TikTok and Instagram, where users apply a specialized filter to mimic the iconic, feminine aesthetic of the Nintendo princess. Originally gaining traction alongside the hype for The Super Mario Bros. Movie, the meme typically highlights a dramatic 'glow-up' transformation or applies the hyper-feminine, sparkly filter to tough or unexpected characters for a hilarious contrast. It has become a staple for creators wanting to showcase their favorite 'girly' edits or to poke fun at the perfection of social media beauty filters through the lens of Mushroom Kingdom royalty.
