http://en.wikipedia.org/wiki/HoundstoothHoundstooth, hounds tooth check or hound's tooth (and similar spellings), also
known as dogstooth, dogtooth or dog's tooth, is a duotone textile pattern characterized by broken checks or abstract four-pointed shapes, often in black and white, although other colours are used. The classic houndstooth pattern is an example of a tessellation.
A smaller scale version of the pattern can be referred to as puppytooth.[1][2]
Kind of helps explain the wimmen folk.
