About Us

At Big Day Tees™ we believe every day is worth celebrating, birthdays, weddings, baby showers, graduations, and even Tuesdays that feel like Fridays.

Born from a love of life’s big (and little) moments, our tees are designed to bring joy, spark laughter, and make memories you’ll want to wear again and again.

Designed in love by our design team in New Zealand and then custom-printed just for you, with love, sprinkles, and a dash of confetti magic. 

Whether you’re throwing a party, planning a proposal, or just want the world to know it's your day, we’ve got the perfect tee for that.

Let’s turn your “just another day” into a Big Day. One tee at a time.
