The good girl/bad girl playoff is well-trodden fashion ground (think Britney Spears in Toxic). Suki Waterhouse is channeling both sides of womankind in her night-out look here. Good girl sleek hair extensions / bad girl handcuffs. Nice hair slides / naughty chains. Sweet centre parting / deadly knuckledusters. It’s a potent showdown that totally works for your own party look: beguiling – with bite.
