The good girl/bad girl play-off is totally common 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 clips/naughty chains. Sweet center-parting/killer four-finger rings. It’s a potent showdown that totally works for your own party look: beguiling—with bite.
