Elie Saab and Mario Sorrenti took to the streets of Chicago last weekend for an upcoming fashion campaign said to feature German model Toni Garrn—and a one-of-a-kind gown. The three-day production, which brought a crew of about 60 people to town, started Saturday, with rainy weather forcing production indoors at Essanay Studios in the Goose Island neighborhood.

Filming continued on Sunday at the Jackson Street Bridge and LaSalle Street and wrapped up on Monday on the steps of the Museum of Contemporary Art.

Rich Moskal, director of the Chicago Film Office, said the idea was to show a model in a “large urban skyscraper canyon. Chicago was in the backdrop, whether it’s the Board of Trade, the Rookery Building, the Bank of America or the Jackson Street Bridge. They liked the look of Chicago’s bridges in particular,” Moskal said. “We offered a big city aesthetic with an abundance of bridges that fit their vision in terms of what this campaign was supposed to look like.”

The production included still shots as well as video shot outdoors. “Nobody was happy about the weather, but fortunately it did clear up and gave them adequate time to get the work they needed to done. It’s the nature of filming outdoors,” he said.

Moskal said Elie Saab’s team approached the city about a month ago to shoot there. “The city offers a very cinematic look,” Moskal said, noting that over 450 productions were shot in the Windy City in 2014. “We’re also very affordable and we have the ability to close streets and bridges, making it possible to get the work done.”
