The Metropolitan Museum announced on Wednesday that it would keep its "Alexander McQueen: Savage Beauty" exhibition open until midnight on Aug. 6 and 7, the last two days the show will be open. The late-night hours mark the first time in the museum's history that it has had its doors open until midnight.

"Savage Beauty" opened on May 4 to record-breaking crowds — the public opening-day attendance surpassed that of all previous Costume Institute exhibitions. Of past shows at the Met as a whole, the only show with better opening-day attendance was "Vincent van Gogh: The Drawings" on view in 2005.

The McQueen show was originally scheduled to close on July 31, but the Met announced in June it would extend the show by a week. By close of business on Wednesday, the museum expected 550,000 visitors would have seen the show.

Last week, The Met announced it had broken records: 5.68 million people visited its Fifth Ave. location, its Cloisters museum and its gardens in the past fiscal year. The number marked the most visitors the Met has had in 40 years.
