Normcore is when people decide to wear regular, simple clothes that they could find anywhere. They try to look like they're not trying to be fashionable, but they still end up looking cool. It's like when you put on your favorite t-shirt and jeans, and you feel comfortable and relaxed. That's normcore.
It's kinda like a big trend, where people started to like plain clothes that are easy to wear and not in fashion. It's like a reaction against fashion trends and standing out. Instead, people want to look like they're blending in with everyone else.
So, if you see someone wearing plain white sneakers, a basic t-shirt, and blue jeans, they might be normcore. But don't worry, it's not boring, it's just a different way of being fashionable!
