If Kate Moss can make it here, she can make it anywhere.
But just in case, superstar Jennifer Lopez was on hand to give the launch of Sir Philip Green's first US Topshop store a helping hand.
J-Lo gave the event, a star-studded dinner on the eve of the public opening, the A-list seal of approval. Mail Online reported.
Wearing a white strapless sheath which clung to her every curve, she certainly upstaged Kate who wore a tiered minidress with her favourite tuxedo jacket, black tights and heels.
The pair, who are not known to be friends kissed and greeted one another like old pals on the red carpet, and later posed up for photographs with Topshop owner Sir Philip Green.
Also in attendance was the grande dame of fashion Anna Wintour, Blondie star Debbie Harry and actress Rosario Dawson.
