Lofi is a chill aesthetic taken from lo-fi hip-hop culture, built on cozy study atmosphere, anime backgrounds, and a relaxed mood, popularized by YouTube study streams around the idea of calm productivity. Oversized hoodies or sweatshirts are the core. Vintage band tees and thrifted sweaters cover the rest. Simple wide-leg pants go below, with low-key accessories completing a studious, unhurried look.
