From “balletcore” to “bloke core,” niche style movements dominate 2025. These “core” aesthetics, born online, capture moods and microcultures. Balletcore brings pastels, leotards, and leg warmers; dark academia leans on tweed, turtlenecks, and brooding palettes. Blokecore references ‘90s sportswear and football fashion. Each aesthetic is highly visual and driven by social media platforms like TikTok. Fashion is now about belonging to a visual narrative or subculture. These cores let wearers express identity, nostalgia, or fantasy—blurring the line between costume and clothing. In a hyper-curated world, fashion tribes are thriving through these stylized themes.
