Along with the colder weather, the holiday season heralds in a full social calendar that requires a wide range of wardrobe options. For the most formal occasions, a sharp tuxedo with satin lapels makes an indisputably timeless statement. If you’re a bit bolder, a suit in Highland red or Blackwatch tartan is a dramatic look. Suit separates are also dapper options for events all season long. For more informal cocktail parties, a velvet blazer adds a rich, luxurious layer to a dressed-down outfit—for example, a button-down oxford paired with dark denim—and can be worn over anything from a shirt and tie to a crewneck sweater. And if you receive an invitation to an event with a dress code that falls somewhere between formal and informal, break out your go-to classic suit in charcoal or black. Your furnishings, like novelty cuff links or a tie in a standout color, will help you make a personal style statement.
