A bow-tie is usually preferred for black tie, but there are a few reasons you might choose a tie. You may have a more rebellious personality, you might not feel comfortable in a bow tie yet, or you may be a larger guy. Particularly for the latter, a tie can look more flattering as the length helps to draw the eye down and creates less white space. With a classic tuxedo, a tipped tie could be quite an understated statement. On the other hand, if you were to wear a double-breasted tux with wide lapels like, say Lapo Elkann, it would make you stand out.
Whichever you’re going for, if you’re pushing the boundaries of black tie, Jasper says it’s important to show that your neckwear is a considered choice. He picked a black grenadine tie because the texture and material shows an appreciation of craftsmanship and attention to detail. You can wear any plain white shirt as you will not see much of it. To tie it all together, he picked the patent Derby, also known as the smoking shoe, as it has a slightly slimmer appeal and feels more slick.
