Many features can be considered typical characteristics in a blazer. Commonly, blazers feature structured shoulders that aim to provide a broader silhouette, a button-down front closure, and a lapelled collar.
However, there is plenty of wiggle room in blazer features. For example, some blazers boast vented hems, a lined interior, and button fastened cuffs. The blazer has come a long way in terms of design, meaning there are now more variants.
