Merchandise & Retail Design

For the 25th anniversary of Mamma Mia! on Broadway, I led the design and creative direction for a full line of merchandise, balancing fun, theatricality, and brand consistency for both casual fans and devoted theatergoers.

Case Study

The Broadway revival of Mamma Mia! demanded a merchandise collection as celebratory and playful as the show itself. I designed an entire line of products, from apparel and pins to totes and souvenir books, ensuring each item resonated with multiple audience segments while staying true to the show’s iconic brand.

The Challenge

  • Extremely tight timeline: 30 design concepts to be produced in two days

  • Diverse audience: Must appeal to bachelorette parties, multigenerational families, and longtime fans

  • Brand integrity: All designs had to align with established show identity while feeling fresh

The Approach

  • Rapid audience research to understand different fan segments

  • Developed multiple design directions: subtle, upscale pieces vs. bold, theatrical designs

  • Streamlined production workflows for fast, high-quality delivery

The Work

  • Designed 30+ pieces, including logo tees, pins, tote bags, and a program.

  • Crafted cohesive color palettes, typography, and vector illustrations to unify the collection.

  • Produced high-fidelity mockups and provided all final assets ready for both print and digital merchandising platforms.

The Impact

  • The collection launched successfully time at the Winter Garden Theatre and Playbill.com.

  • Multiple items sold out quickly, demonstrating strong audience engagement.

  • Show producers praised the merchandise for enhancing the overall theater experience.
