The Directoire style reflected the values of republican Rome. Revolutionary emblems could be found on furnishings, decorations and textiles. The furniture was meant to be a copy of relics discovered in the excavations of Pompeii, or be inspired by representations of antiquity in general. Furniture and ornaments were less used, simple lines were important in this style. Mahogany was a key element.

Clothing and Fashion
It was a classical style, based on an idealization of ancient Greek and Roman dress with narrow skirts. In this period the willingness to expose the breast started to affect fashion. The style was appropriate for a pregnant or nursing woman as the breasts were exposed and their availability was improved. Maternity became fashionable and it was common for women to walk around with their breasts exposed. White was considered the perfect colour for neoclassical style of clothing.
