The Dream Downtown was the place to be, Fashion Week party or not, on Saturday night.

Designer Prabal Gurung hosted a post-show dinner for family and friends — including Candice Swanepoel, Maggie Betts and Brad Goreski — in the Presidential Suite, followed by a party DJ'd by Mia Moretti, while "Project Runway" winner Christian Siriano threw a bash at the PH-D Rooftop Lounge.

After Siriano’s crew cleared out at midnight, celebs including Sofia Vergara headed up to PH-D for drinks — as well as a mini Whitney Houston tribute that was led by actor Edris Elba.

“He asked the crowd to hold their glasses in the air in honor of a legend we all lost today,” a witness told amNewYork.

The Dream's restaurant, Marble Lane, was also studded with stars that night — Justin Bieber and mentor-pal Usher ate a late dinner, and Kellan Lutz dined with a group of eight.
