How to measure

Lay a favorite tee flat.
Measure across the chest 1″ below the armhole (that’s your chest width).
Measure from the highest shoulder point to the hem (body length).

Measurements are of the garment, not the body. Allow ±1″ / 2.5 cm tolerance.

Variant

A clean, bold graphic: a bright orange pumpkin with the π symbol carved through the center and a pop of green on the stem. The distressed texture gives it a vintage, chalk-dust vibe, and the high contrast on black makes the design read from across the room.

It’s playful nerd humor for spooky season—clever without being loud. Great for classrooms, math club nights, hackathons, or any October outing where you want a smart wink to Halloween.
