le Bonnet Rouge, Phrygian Cap, Cap of Liberty [more info]: Borrowed from Roman tradition, the bonnet rouge became a symbol of liberty during the revolution. And is apparent to this day in french national iconography.
An elongated soft woolen cap with the tip pulled forward, it became an every day staple of revolutionary dress, particularly by the sans-culottes.
The Tricolour Cockade: A roundel of ribbon to be worn mostly on hats. in 1789 the tricolore was adopted as a means to declare your revolutionary sympathies, and later as a national symbol of the new France. By July 1792 a law was passed making it mandatory for all men to wear the tricolore cocarde. The following year the Societé des Républicaines-Révolutionnaires, a fervently Republican club of middle and lower class women, took to the streets threatening to whip any woman who failed to don their cockade, even though the wearing of them had not been mandated for women. So they petitioned the Convention requesting such a law make it on the books.
