However, it's often used in a more figurative sense to mean:
* Two-sided fashion: This could refer to clothes that are designed to be worn on both sides, or to a fashion trend that encompasses both masculine and feminine styles.
* Fashion that is relevant from both a front and back perspective: This could refer to clothes that look stylish from all angles, or to a fashion trend that is both aesthetically pleasing and practical.
The phrase is often used in the context of fashion design and criticism, but it can also be used more broadly to describe any situation where there are two sides to something.
