Once Upon a Princess

Vendor Partnership Guide

Welcome

Step into a world where elegance, storytelling, and celebration come together.

Once Upon a Princess is a luxury quinceañera showcase created to connect Utah's premier event professionals with families actively planning their 2027 quinceañeras. Hosted at the stunning Belvedere in Provo, this one-day experience is designed to inspire, educate, and immerse guests in the possibilities of creating a truly unforgettable celebration.

Unlike a traditional expo, Once Upon a Princess is an immersive experience. Every detail—from the venue and décor to the fashion show and entertainment—is curated to reflect the grandeur of a royal celebration.

The heart of this year's theme is Three Princesses, each representing a unique vision of a modern quinceañera. Throughout the event, guests will follow three distinct stories brought to life through couture gowns, editorial styling, and thoughtfully designed experiences.

Our goal is simple: create the most memorable quinceañera showcase in Utah while providing vendors with meaningful opportunities to connect with highly qualified families who are ready to begin planning.
