Despite the optimism that preceded his second summit with North Korean leader Kim Jong-un, the two leaders ultimately failed to reach an agreement.

The president made a strong impression in his black suit and blue tie on the second day of the summit with North Korean leader Kim Jong-un.

He had worn a black and pink striped tie at Wednesday's meeting. Classic solid ties have been his preferred choice on most occasions, with stripes used rarely.

According to The New York Times, statesmen tend to pick the color of a tie depending on their political message.

The Pantone Color Institute says blues are a color range of infinite possibilities. In particular, it is a color preferred by Americans, French, Canadians, Australians and New Zealanders.

"Blue is the color of constancy. With most connections to blue derived from a non-turbulent sea and sky, the human mind embraces the concept of blue as tranquil and constant, translating this color range into a symbolic image of dependability and trust."

Karen Schloss, an assistant professor of psychology at University of Wisconsin-Madison, explained on Artsy: "It turns out, if you look at all of the things that are associated with blue, they're mostly positive. It’s really hard to think of negative blue things."

In 2016, former president Barack Obama wore a blue white striped tie during his visit in Vietnam.

According to Masculine Style, President Trump has an interesting taste for this fashion staple. It is his custom to wear an eye-catching and colorful tie, highly contrasting with a dark-colored suit. He regularly makes appearances in ties that extend below his belt seeing that they have a "slenderizing" effect on the torso.
