Hippotenuse — The Cute Maths Geek T-Shirt Show off your inner geometry geek (and your excellent taste in puns) with our Hippotenuse tee. A cheerful hippo in full professor regalia struts confidently across the chest, declaring that being “sqrt(hippo² + tenuse²) = awesome” is the only theorem that matters. It’s the perfect conversation-starter for study group, maths club, or laid-back weekends when you want your humour as crisp as your angles. Why you’ll love it Maths-class meets streetwear – playful graphic that only the initiated will fully get. Soft, breathable cotton knit – comfy enough for marathon revision sessions or all-night coding sprints. Unisex regular cut – neither boxy nor clingy; sits just right on every body type. Colour-fast print – bright pigments that stay sharp wash after wash. Find your fit (read this part!) Our shirts follow ASIA sizing, which runs about one to two sizes smaller than standard US/EU cuts.

When in doubt, lay your favourite tee flat, measure bust width and length, and compare. Care instructions Machine wash cold, inside-out. No bleach or harsh detergents—keep that hippo happy. Tumble dry low or hang dry for longest life. If ironing is a must, press inside-out, avoiding the print.
