What is a common characteristic of a blazer?

A blazer is typically recognized for its structured shoulders and tailored fit, which contribute to its polished and sophisticated appearance. This design aspect is central to the blazer's versatility, allowing it to be worn in both formal and casual settings. The shoulder structure helps create a defined silhouette, which is a hallmark of tailored garments, giving the wearer a chic and put-together look.

The other characteristics mentioned in the other options do not align with standard features of a blazer. For example, while some blazers can be worn with skirts, it is not a defining characteristic since they can also be paired with trousers, jeans, or shorts. Denim blazers do exist, but they are less common, and blazers are traditionally made from more tailored fabrics such as wool or blends that enhance their structured nature. Lastly, blazers typically do not have hoods, as they are designed to convey a more formal style, whereas hoods are often associated with more casual outerwear.
