When should you wear a suit without a tie? I believe the times have changed enough that if you wear a nicely tailored suit, a nice dress shirt, and appropriate shoes (Do not wear sneakers with a suit. You’re not hip, you’re out of touch), you are most definitely the best dressed person in the room.
I love ties, but I feel over dressed when I wear one unless it’s a formal gathering. I do however, wear a pocket square stuffed into my suit pocket as though it was a last minute thought. I love the puff pocket square look because it appears as though you’re not trying too hard, but it can add color, or a little flare to the look.
Yes, wear your suit without a tie. You still look good player. Gary Oldman pulls it off nicely too.
