Describe a classic men's haircut.

The classic men's haircut often features a tapered style that is longer on top and shorter on the sides. This look is popular due to its versatility, allowing for a range of finishing styles, from more casual to polished looks. The longer hair on top can be styled in various ways—slicked back, textured, or even styled into a quiff—while the shorter sides provide contrast and a neat appearance. This type of cut enhances the structure of the head and can be adapted to suit different face shapes and personal preferences.

Other styles mentioned, such as equally long all around, are less common in contemporary classic cuts, which typically seek to create definition and shape through variation in length. A messy, layered look tends towards a more modern and casual aesthetic, which is not representative of the traditional classic men's haircut. While a buzz cut is uniformly short and can fit into the broader category of men's hairstyles, its lack of variation in length does not align with the tapered style that has classic roots.
