1. Pair an Ascot with a tux for unique formal look to a formal reception or wear it under a button-down shirt and a blazer or sports coat for a dressier look for night out or a date.
2. Contrast colors. Pair lighter-colored ascot with dark shirt, and dark colored ascot with a light shirt and dark jacket.
3. Keep the fabrics consistent. Wool and cashmere blends complement a heavy tweed sport coat, while a silk ascot will be dashing with lightweight wool blazer.
4. Avoid wearing ascot with crewneck shirt or any sweater.
