The Ultimate Guide to Internet “Cores”

So... What Is a “Core,” Anyway?

Scroll long enough on TikTok or Pinterest and you’ll spot a pattern: everything is a core now. Tomato Girl. Clean Girl. Blokecore. Even Recessioncore.

The word “core” has become internet shorthand for a hyper-specific aesthetic or lifestyle, usually based on how something looks, but can also be tied to mood, media, or identity.

Think of it as a vibe you can wear, post about, and sometimes even build a personal brand around. What started with “normcore” back in the Tumblr era has now exploded into a full-blown culture of micro-aesthetics.

Why Are There So Many “Cores” Now?

The short answer? The algorithm. Platforms like TikTok reward niche content, and “cores” are hyper-niche.

They’re visual, they’re trend-friendly, and they give people a fun way to signal identity or aesthetic taste without needing to explain it.

Also? Monetization. These vibes sell well. Once an aesthetic takes off, it’s easy to attach a product to it—clothes, playlists, journaling tools, skincare, digital downloads, basically anything you can think of to sell.

Brands are watching, and so are creators looking to build niche communities.

How “Cores” Became a Business

Once a core gains traction, it becomes prime real estate for monetization. Here's how creators and brands are cashing in:

• Influencers build content around their aesthetic (from Clean Girl GRWMs (get ready with me) to Cottagecore day-in-the-lifes)

• E-commerce brands tailor drops or marketing campaigns to current cores

• Etsy sellers offer themed downloads, journaling tools, planners, and printable mood boards

• Amazon storefronts filled with core-aligned “must-haves”

Cores aren’t just vibes. They’re mini-economies.

Core Fatigue Is Real Though… Kind Of

With new aesthetics dropping weekly, it's easy to feel burned out. But here's the twist: you don’t have to pick one. Most people jump between them or mix and match based on mood, season, or what's trending.

No gatekeeping here. If you want to be a Clean Girl on Monday and a Tomato Girl by Saturday? Do it!

Mixing is the best way to experience these cores as just one may not be your thing, but certain elements from a bunch can do the trick.

Some have names, some don't, like I will never get tired of "Coffee Core", not sure that's a core, but coffee culture is EVERYWHERE.

The Next Wave?

Our bet’s on Cloudcore, a dreamy, clean-tech vibe blending transparency, light, and soft futurism. Think: AI lifestyle mixed with Pinterest minimalism. Or maybe Sleepy Girl Core, because burnout is real and rest is hot. 🤣 🤦🏾‍♀️

But honestly? The next core is already in your saved TikToks.

“Cores” may sound silly, but they’re the internet’s favorite way to express identity, mood, or just have a little fun. Whether you’re building a Pinterest board or launching a side hustle, tapping into aesthetic trends is one way to stay in the loop and make it your own.

Scroll your vibe. Remix the aesthetic. Start your core era.
