Did Coca-Cola Advert Change Santas Suit?

The Coca-Cola advert did not change Santa's suit.

The advertising campaign for Coca-Cola played a significant role in shaping the public's perception of Santa Claus. Prior to the campaign, a variety of different depictions of Santa existed. However, the Coca-Cola's advertisements, created by artist Haddon Sundblom in the 1930s, popularized the image of Santa as a plump, jolly man with a white beard, rosy cheeks, and a red suit trimmed with white fur. This image has become the standard representation of Santa Claus in popular culture.
