Paul Costelloe showcased his Autumn Winter 2025/26 collection at London Fashion Week, drawing inspiration from his equestrian-themed designs from the Eighties and Nineties. The collection featured traditional green Harris tweed, earthy tones, and lush textures, blending country style with city chic.

The collection included a variety of looks such as cropped jackets, A-line coats, fit and flare dresses, and monochromatic ensembles. The designs incorporated wool, tweed, and velvet fabrics in neutral tones and bold colors, with a focus on classic silhouettes and romantic botanical prints.

Accessories such as long gloves, knee-high boots, and vintage-style jewelry added an extra layer of richness to the luxury looks. The show was well-received by the audience, including celebrities like Jodie Kidd and Vanessa Williams, showcasing Costelloe’s ability to create covetable and contemporary designs even after a 60-year career in fashion.
