The Sibling Code Collection: Built-in Best Friend... With Attitude

For the person you're stuck with for life, who is also, coincidentally, your best friend. This design is the most accurate job description ever created for a sibling. It’s a loving tribute to the person who will share your secrets, steal your clothes, and have your back, all with a healthy dose of sass.

 

Design Story

This design perfectly captures the beautiful duality of a sibling bond. It starts with the heartwarming truth, "Built-in best friend," rendered in a soft, elegant script, symbolizing the deep, unbreakable connection. Then comes the inevitable and hilarious reality check, "...with attitude," presented in a strong, bold, all-caps font. The contrast in styles is a visual representation of the relationship itself: a foundation of love and friendship, generously sprinkled with sarcasm, eye-rolls, and unfiltered opinions.
