Three teenage girls strike playful poses against a stone wall, each dressed in a distinct 90s-inspired “nerd” costume: one in a blue plaid shirt with knee-high socks and black leggings, another in a vibrant tie-dye top with suspenders and jeans, and the third in a pink tee with denim shorts and neon socks. All hold vintage TI-83-style graphing calculators and wear oversized, colorful eyeglasses, embodying a humorous, confident take on academic chic.
