Liliana Dress & Rita Hat

Notably, the collaboration features Cefinn Founder and Creative Director Samantha Cameron’s headpiece, which she wore to the King’s Coronation in May 2023 — the inspiration behind our continued partnership.


We caught up with Jess to discuss the evolution of our collaboration, her design inspirations, and her top Ascot styling tips for 2025!


“It was great to work with an open brief - I feel like the possibilities grow larger and seem to flow in a really creative way when you have two heads working together on one project. It’s so special seeing sticky notes and sketches flourish into the finished selection.

Together, with Sam and the team, we made our final selections and got cracking! After lots of planning, tweaking and refining, there’s nothing more exciting than seeing the final campaign come to life!”

Jess' Ascot Rules

DO
  • When choosing a hat or headpiece, look at the whole silhouette of your ensemble rather than just focusing on what suits your face shape.
  • Always wear an upturned brim because they’re always flattering—especially if you want to create the illusion of height.

    • DON'T
  • Don’t wear a brim that’s wider than your shoulders or hips unless you’re tall.
  • Don’t let your hat wear you—always make sure you feel comfortable!



    • “Millinery is a skill and an art, it is the ultimate in creative expression within fashion. I went to Jess originally for my bespoke Coronation headpiece because I have always admired her style and flair and after the success of our first collaboration last year, I knew I wanted to work with her again.”
