Luke Grimes (born 21 January 1984) is an American actor and musician best known for his role as Kayce Dutton in the hit series Yellowstone. With his understated intensity and rugged charm, he’s become a fan favourite on the neo-Western drama, portraying the conflicted yet loyal son of Kevin Costner’s John Dutton. Prior to Yellowstone, Grimes built a diverse portfolio with roles in American Sniper, The Magnificent Seven, and the Fifty Shades trilogy, proving his versatility across both blockbuster films and prestige television. More recently, he has explored his passion for music, releasing country-inspired tracks that reflect his Montana-based lifestyle.

Grimes’ style is rooted in modern Americana, balancing rugged workwear with polished casual pieces. His look often leans into denim, leather jackets, and classic boots, a natural extension of his Yellowstone persona. Eyewear adds a refined edge—he gravitates towards timeless aviators, earthy-toned acetates, and subtly retro frames that complement his laid-back yet masculine aesthetic. Brands like Oakley and Oliver Peoples, with their heritage designs and enduring craftsmanship, perfectly align with his understated cool. Grimes’ eyewear choices mirror his screen presence: quietly magnetic, effortlessly stylish, and deeply authentic.
