Old Mexican man, with his inquisitive gaze and enthusiastic demeanor, would approach a modern cowboy and rancher style with a sense of exploration and adventure. He might wear a rugged chambray shirt in a classic denim hue, paired with durable khaki trousers or jeans that offer both comfort and functionality. Instead of traditional cowboy boots, Arthur might opt for sturdy leather work boots with reinforced soles and practical detailing, reflecting his practicality and love of tinkering. His trousers would be neatly tucked into his boots, giving him a polished and put-together look. For headwear, Arthur might choose a weathered leather hat with a wide brim, adorned with a simple leather band or decorative stitching for a touch of rustic charm. A leather belt with a vintage buckle would cinch his waist and add a touch of personality to his outfit. With his wand tucked securely into a pocket and a curious glint in his eye, Arthur Weasley would embrace the modern cowboy and rancher style with his own unique brand of enthusiasm and charm, bringing a sense of adventure to the Wild West.
