About

Hi, I'm Stephanie Su — founder of Wonderful World Design.

I'm a scientist by training, with a PhD in social science, and a lifelong tennis lover by heart. I never chased a pro career on the court, but I've never stopped loving the game. For me, tennis has always been more than a sport. It's a lifestyle. A way to stay healthy, present, and connected to the people around me. A reminder that what matters isn't how well you play — it's how much you love playing.

Our Promise
Every piece we release is one we'd wear ourselves. We design slowly, refine relentlessly, and only release something when the quality matches what we'd want for our own collection. We work directly with skilled manufacturers and reject far more samples than we keep. Whether it's a necklace, a bracelet, or something we haven't even imagined yet — the standard is the same: made with care, built to last.

What We're Building
Wonderful World Design is a tennis-inspired lifestyle brand for people who love the sport and the life around it. We're starting with jewelry — wearable, everyday pieces that let you carry your love for the game wherever you go. Over time, you'll see us expand into other lifestyle essentials, all designed with the same care, all created for the community that makes tennis what it is.

This isn't a fast-fashion brand. We don't chase trends or release new collections every season. We design intentionally, drop in limited quantities, and put our energy into pieces that mean something.

Our Mission
A portion of every sale supports animal rescue — because the love and care we bring to the things we make should extend to the world beyond us.

We believe small businesses can do business differently. We believe craft still matters. And we believe the things you wear should reflect who you are.
