A regal reimagining of a classic silhouette, The Royal Mariner Romper is part of our exclusive collaboration with Historic Royal Palaces. Inspired by 19th-century sailor suits worn by royal children, this limited-edition piece blends timeless design with thoughtful practicality for little ones. Crafted from crisp cotton, the romper features a traditional mariner collar trimmed with elevated gold rope detailing and subtle ceremonial touches. Structured yet soft, it’s fully lined for comfort and finished with elasticated leg cuffs to allow for ease of movement and effortless changing. A heritage-inspired romper designed to be cherished and passed down—perfect for marking special moments in your baby’s early years.
