"Rough around the edges" is an idiomatic expression used to describe something or someone that is not perfect or polished, but rather appears to be unfinished or unrefined in some way. It suggests that there are imperfections or flaws in a person or thing's presentation, behavior, or personality, which can make them seem raw or unpolished. This can be applied to a wide range of situations, from a person's appearance, to their behavior or communication style, to a product's design or construction. However, it can also be used in a positive way, implying that the person or thing in question has a certain authenticity, charm, or roughness that makes them unique or interesting.
