Incroyables and Merveilleuses were the dandies and fashionistas of the revolutionary period. Today, Directoire style evokes glam rock, Marat/Sade, and John Galliano. The style famously inspired Galliano’s 1984 graduation collection, entitled Les Incroyables, as well as his work for Givenchy.
Here are the museum notes:
This handsewn silk tailcoat, with its high collar, wide lapels, short front, and long back exemplifies how French fashion extremists (incroyables) adopted and exaggerated traditional wool riding coats from England. The sleeves of this tailcoat, set unnaturally close together, forced the wearer to hold his shoulders back and thrust his chest forward to create a “pouter pigeon” silhouette which was fashionable in the late eighteenth century.
