Whitney dressed as Britney

A modern take on the, "Mutton dressed as Lamb" phenomenon, whereby women old enough to be your mother, dress as though they were young enough to be your little sister.

Lad A: What do you reckon of her at the bar mate?

Lad B: Whitney dressed as Britney mate, saw her smoking outside. Old enough to be your mother.

Lad A: Yeah, it's pretty dark in here.
