Katy Perry's latest fragrance went on sale Wednesday — on Twitter. Mad Potion can be purchased in the @KatyPerryPopUp using Twitter's Buy Now card, and buyers will have access to some "exclusive Perry content," WWD reports. It makes sense since Perry's main Twitter feed has more than 72 million followers. (The fragrance will hit bricks-and-mortar stores later.)
The Met Costume Institute's "China: Through the Looking Glass" exhibit, which opened May 7, is proving to be popular. It welcomed its 500,000th visitor Tuesday and is on track to surpass the record-breaking "Alexander McQueen: Savage Beauty" exhibit of 2011.
