Hilary Swank hosts Calvin Klein 25th Anniversay bash at New York Fashion Week

However, those who did manage to get past the velevt rope of the Calvin Klein Underwear party celebrating 25 years of the iconic undies included Fergie (the singer not the Duchess), Jaime Burke (Sienna's ex), Sophia Bush, Rachel Zoe, Amy Sacco, LL Cool J, and a clutch of models including our very own Agyness Deyn, Jessica Stam and Pete's new squeeze Irina Lazareanu. Hilary Swank and her co-host, actor, and face of Calvin Klein 'Steel', Djimon Hounsou transformed CK's 39th Street H.Q in to a huge 'steel box'. Suspended above the bar in a fortified plexi glass cube, models paraded Calvin Klein underwear all night while guests frolicked between the custom made steel dancefloor and huge white pillowy sofas, in the main arena and VIP lounge. "Working with the Calvin team is like being part of someone's family" said Hilary of her assocciation with the label. We don't know about you Hil, but our family do's sound nothing like this extravaganza!
