More than a shirt — it’s a declaration of elegance, discipline, and rebellion against spaghetti code.

Clean Code

🧠 Coders don’t wear clothes — they wear philosophies.

You could wear any T-shirt.
Or you could wear a manifesto.

“Codex Mundus” is more than a design — it’s a symbol for developers who believe that elegance in code reflects elegance of mind.
It’s the secret handshake for people who refactor before they rest and who find beauty in braces and balance.


⚙️ Designed for developers who think in syntax and style

  • Inspired by the Agile Software Coloring Book — the humor, the Latin flair, the devotion to clarity.
  • Typography that commands respect — minimal, bold, and instantly recognizable across a crowded dev meetup.
  • Soft premium fabric — feels as good as a perfectly formatted pull request.
  • Gender-neutral fit — because good code has no ego.
  • Subtle humor, serious intent — a quiet protest against technical debt everywhere.

💬 What it says without saying a word

“Yes, I lint my code.”

“No, I don’t merge without review.”

“Clean code isn’t a rule — it’s a religion.”

This shirt sparks conversations, smiles, and the occasional respectful nod from the senior dev across the room.
It’s not fashion — it’s reputation management.


☕ Where to wear it

  • Team meetings (for when you need moral superiority without saying a thing)
  • Hackathons (pairs perfectly with caffeine and chaos)
  • Remote calls (bonus points if someone asks what Codex Mundus means)
  • Casual Fridays, conference stages, or anywhere code quality still matters

💡 Why you’ll love it

Because it’s not just another shirt.
It’s a manifesto in cotton.
A small rebellion stitched in Helvetica and wit.
A daily reminder that clarity is cool and readability is rock-and-roll.


Wear it. Ship it. Refactor the world.
