60s Chic is a style of fashion that was popular in the 1960s. It was characterized by bright colors, geometric patterns, and bold accessories. The term MOD, which is a 3 letter acronym, is often used to describe this style. MOD stands for 'Modernism', which was a movement that focused on modern art, architecture, and design. This style of fashion was popularized by the British youth culture of the time, and it has since become an iconic look.
