Jenny Packham has dressed royalty (ahem, Kate Middleton), and this roll-with-it ponytail is just the kind of style the newly minted princess would wear. It's fun, flirty, and fashionable: the perfect look for any commoner to re-create.
The look: A twisted side ponytail, teal eyeliner, and white-out French manicures.
The inspiration: The women who partied beside the Rat Pack in 1960s Las Vegas.
Who would wear it: The tomboy who also reads Vogue on occasion.
