What does muse mean referring to fashion?

A muse in the context of fashion is a person or thing that inspires a designer or artist. It can be anything from a person, such as a celebrity, to a place, such as a city, to an object, such as a piece of art or even an emotion. The designer finds the muse to be inspiring and is inspired to create based on the characteristics or the qualities of the person or thing. The designer might decide to use colors or patterns that they associate with their muse, or they might be inspired by the person's personality or lifestyle.
