Show HN: GPTShirt – Describe shirt. Wear shirt.

Post:

Hey HN! I built GPTShirt to make it ridiculously easy to create and buy good looking custom t-shirts, no design skills required. It's at https://gptshirt.app.

How it works:

1) Describe your idea in a prompt, with optional reference images (people, objects, styles, etc.)

2) AI generates your design. Iterate and refine until happy. Powered by Nano Banana.

3) Order it - we handle printing and shipping

4) (Optional) Share it - handy for group orders.

Some example shirts:

- Family picnic with Totoro - https://gptshirt.app/designs/2910ae97-8c7a-4631-9271-291364f...

- Cosmic Cat Island - https://gptshirt.app/designs/0d65835c-ea70-4a56-9f5e-92a0ec4...

- Tropical Escher - https://gptshirt.app/designs/72cda84a-0862-4499-abf9-39ad3f9...

It costs $20 per t-shirt, plus shipping. Shipping takes 3 to 5 business days.

Would love to hear feedback - thanks for taking a look!
