The heiress opted for a super-loud gown as she stepped out at the Brazil Foundation Annual Gala in New York yesterday (18 September).
Her dress featured a high gathered neckline, floor-skimming design and a lace overlay with intricate beading.
Red lace is a huge trend at the moment, as worn by seasoned fashionista Fearne Cotton. But although we're all for a dramatic frock, we think Nicky's number would have benefited from a lower neckline.
We do love her choice of arm candy though - a boxy clutch adorned with eye-catching diamanté embellishment.
She swept her glossy blonde locks into a chic updo, adding mega-watt false lashes and a toned-down glossy lip.
