Polo neck

[2] From the late 19th century on polo necks were commonly worn by fishermen, manual workers, athletes, sailors and naval officers.

[6] Polo necks also became a big fashion for wealthy young men after they were worn by European film stars Marcello Mastroianni and Yves Montand.

Vladimir Putin[8] of Russia, Andreas Papandreou[9] of Greece, and Emmanuel Macron[10] of France are examples of European leaders who are fond of wearing polo necks.

Absorbed into mainstream American fashion by the mid 20th century, the polo neck came to be viewed as an anti-tie, a smart form of dress for those who rejected formal wear.

[12] Disgraced Theranos founder Elizabeth Holmes deliberately copied Steve Jobs' style in wearing a black polo neck.

Very elegant polo necks of silk or nylon knit, especially made with French cuffs for formal dress affairs, have also seen success in American fashion.
