The Brooklyn Sweater Trend emerged as a prominent aesthetic trope on social media platforms like TikTok and Instagram, personifying the effortlessly cool New York City streetwear vibe. Centered around oversized varsity-style sweatshirts—most notably those featuring 'Brooklyn' in bold block lettering—the trend often involves users showcasing their transition from casual wear to a curated, cozy autumn look. While it started as a genuine fashion movement celebrating thrifting and vintage athletic wear, it quickly became a meme as users poked fun at how the sweater became a uniform for anyone trying to capture the Brooklyn aesthetic regardless of their actual location. The meme is typically used to represent the arrival of spooky season, cozy fall vibes, or the predictable nature of seasonal social media fashion trends.
