Robert Lloyd (18th century) was an English author and artisan renowned for his meticulous treatise, Lloyd's Treatise on Hats, with Twenty-Four Engravings, which merges technical craftsmanship with social commentary. His work explores the aesthetic and functional subtleties of hat design, emphasizing balance between form and utility, as seen in his descriptions of the "Bang-up" and "Regent" styles.
Lloyd also challenges subjective standards in fashion, questioning arbitrary ideas about hat quality. His text, rich in practical detail and wit, reflects a deep engagement with both artisanal tradition and the social roles of clothing. Similar to contemporaries like hatter John Thomson, Lloyd’s work remains a key study in the intersection of artistry and 18th-century commerce.
