Shiralee Grayscale
The fashion crime of wearing two or more clothing items coloured grayscale a the same time. This could be a grayscale top and matching grayscale pants together.
Hey, check it out, that girl over there is wearing grey sweat pants with a grey denim jacket- and oh no... is she wearing a grey headband too! Dear oh dear, she's attempted the Shiralee Grayscale.
