The Caitlyn Jenner transition meme is based on the historic 2015 Vanity Fair cover that introduced Caitlyn Jenner to the world. This template usually features a side-by-side comparison between her previous public identity as an Olympic athlete and her post-transition appearance, symbolizing a massive shift in identity. In meme culture, it is widely used to represent dramatic 'glow-ups,' radical changes in opinion, or the evolution of products and brands over time. While the subject matter is rooted in a significant cultural event, the template has become a versatile tool for any scenario involving a major before-and-after revelation.
