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!


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!
