Blue suits are a staple in any dapper man's wardrobe. Just because they're timeless, however, doesn't mean they have to be stale. With the right styling, you can make this classic feel brand-new again. Here are five ways to nail the blue suit:

1. Keeping it casual
One of the great things about blue suits is that they're endlessly flexible. If you're looking to dress your suit down, wear it over a fresh v-neck t-shirt with a pair of dressy white or tan sneakers. Don't forget the accessories - a colorful watch and a burnished leather belt will bring the outfit together without making it too formal. 

2. Step into summer
Give your blue suit a summer-time glow by pairing it with a pastel oxford. The lighter shirt will provide an eye-catching contrast, and will really show off the tan you've been developing all season. Slip on a pair of wayfarer shades, and you've got an outfit that celebrates summer in style. 

3. Date night chic
Nothing says date night like a suit. Woo your companion by skipping the tie and wearing your blue suit with a floral print dress shirt. The pattern provides texture and an intriguing visual component to the outfit, giving you a look that goes seamlessly from dinner to dancing. Complete the ensemble with a pair of brown dress shoes and a matching belt. 

4. For a formal event
Whether it's a wedding or a job interview, sometimes you need to pull out all the stops. Look your best at your next formal event by pairing your blue suit with a crisp white oxford shirt and a printed silk tie. Keep it in place with a metal tie bar and don a matching pocket square to pull the look together. Remember to unbutton your suit completely whenever you sit down, and leave the bottom button undone whenever you're standing. 

5. Work to weekend
Need a look that's as stylish around the office as it is at Happy Hour afterwards? Wear your blue suit over a striped Henley shirt. Finish the outfit with a pair of leather sneakers, and you have a weekend-friendly look that works just as well Monday through Friday.
