The Geometry Blue Math Button Up Shirt turns number-love into a sharp everyday flex. A blue canvas carries crisp, chalk-style linework—geometric shapes, angle ticks, grid cues, and tidy notations—arranged as a seamless all-over print that lines up across the placket for a clean finish. Built for all-day comfort and movement, with artist-backed artwork printed using earth‑kind inks. Great for class, code, and casual Fridays.
