Design Story

Made for the engineer who still trusts her own calculations more than anyone else’s ‘approximate’ spreadsheet.

When the project manager questions your safety factor, or the client asks if you're absolutely sure the bridge will hold the load, you don't need to show them your massive Excel spreadsheet. You just need to look them in the eye and say, "Trust me, I calculated." Featuring the world's original CPU—the abacus—this design is a sarcastic nod to the rigorous math that keeps the modern world from collapsing. Deployed on our relaxed women's fit (Bella+Canvas 6400). Dedicated STEM clothing designed to provide comfort while you wait for others to catch up to your calculations.

Use Case

Best For

Best for women in data science, finance, or engineering who run the numbers twice and only say ‘trust me’ after the math is clean.

  • Women in STEM.
  • Female structural engineers.
  • Data analysts.
  • Technical professionals who rely on cold, hard data to win arguments.

Signal

Gift Guide

The perfect gift for the female numbers person on your team. If her primary love language is a complex spreadsheet with perfectly formatted pivot tables, this will become her favorite shirt.
