This is the genuine pattern of character. Used throughout history, checkered, plaid or tartan patterns have always been re-interpreted into the present. The most classic convey red, black and white hues with green, blue or yellow highlights while more casual and modern ones bear lighter shades and a chromatic variety.
Is it possible to encapsulate this style into a certain current or fad? Definitely not. It ranges from elegant perennial pieces to fresh spring arrays and counter-movement garments such as those used in punk.
This is character squared simply because it depends on both the designer's purpose and the personality of who wears it to define it's ultimate significance.
