What characterizes a "Bob" haircut?

A "Bob" haircut is best characterized by a blunt cut style that is typically cut at or around chin length. This particular style is known for its clean lines and smooth silhouette, which provides a classic and polished appearance. The defining feature of a Bob is its uniform length, which distinguishes it from other styles that incorporate layers or varying lengths.

In contrast, while options reference other styles, they do not accurately describe the Bob. Styles with layers cut at different lengths do not fit the definition of a Bob, as this haircut is known for its simplicity and lack of layering. Similarly, a hairstyle featuring long bangs and short sides describes a different look altogether, often associated with pixie cuts or asymmetrical styles, rather than a traditional Bob. Lastly, a haircut that tapers towards the back typically reflects styles such as fades or undercuts, which again does not capture the essence of the Bob.
