Vichy check is a fabric pattern for shirts and blouses consisting of stripes of equal width that cross over to form checks. The intersections are in a darker colour than the stripes. The stripes are usually offset against a light-coloured background. Mostly it's blue or red on a white background.
Vichy houndstooth check is a pattern produced in twill weave with diagonal extensions - as opposed to the rectangular extensions in plain-weave houndstooth check. Vichy houndstooth check must not be confused with Vichy check.
Clothing from the 1920s to 1990s is referred to as vintage. However, even new clothes that show particularly typical features of a previous epoch have a vintage touch and are therefore referred to as such. Such features are characteristic patterns, colours, cuts and fabrics that were fashionable in the past.
