Special Agent Thornton The Belted Field Jacket | Gunmetal [Grey Denim]
Regular price £225
Estimated Landing: October 2025
The Special Agent Thornton Jacket is a tailored, military-inspired piece that has become a true Donna Ida wardrobe hero. Cut to the waist with a belted tie to cinch the silhouette, it features front patch pockets, tonal stitching, and signature silver hardware.
Now available in Gunmetal, crafted from soft velvet, Special Agent Thornton brings an elevated twist to this enduring style. The plush texture adds depth and versatility, making it just as easy to wear casually by day as it is to dress up for evening.
Designed to be worn with the Kate in Gunmetal for a perfectly matched look, this is a jacket you’ll reach for again and again.
