Studio Sunday

About Us

More than just clothes—they’re personal items with meaning.

Studio Sonntag – that’s us: Heiko & Sven. Two childhood friends.

The idea came about when we wanted to do something nice for a mutual friend. We designed a personalized T-shirt for him, his wife, and each of his children, featuring matching designs. The enthusiasm and gratitude we received inspired us to make this customization option available to everyone.

Today, we transform basics into truly one-of-a-kind pieces: personalized, high-quality, and sustainable. Each item is crafted with attention to detail, fairly produced in Germany using certified materials, and designed to bring you joy for years to come.

We’re not about mass-produced goods—we’re about stories: your images, your words, your memories—things that bring people together. We hope you enjoy browsing and creating.

Our Promise

Shopping with us is stress-free and risk-free. With our 30-day satisfaction guarantee, you’re in good hands. If something isn’t quite right, we’ll take care of it personally—fairly, directly, and hassle-free.
