Off By One: shirts for code reviewers

Editorial interest 79/100 Selection signal · not a rating of the site

A Toronto developer’s one-person shirt shop turns familiar programming bugs and code-review pain into wearable jokes.

Landing page captured for the 2026-09-03 issue.

Field notes

The shop divides its catalog into “evergreen” designs and short-lived Friday drops, using filenames and terminal-like labels as part of the storefront’s presentation. The currently listed evergreen item is “fine-ill-build-my-own.svg” at $49.99, and the page displays a JavaScript-style example whose array access returns undefined. The owner says they design, print, and ship each drop personally from Toronto.
