Riri arrives at the brand-new multi-billion dollar complex, looking comfy in an Acne pajama-styled attire that she pairs with red lipstick, black nail polish and Manolo Blahnik sandals.
Rihanna had a rather unusual fashion choice when attending the grand opening of Jay-Z's 40/40 club at the Barclays Center. The singer, who's dubbed 2012 fashion risk taker by PEOPLE, donned a silk pajama-styled printed number from Acne's Resort 2013 collection.
The Bajan singer elevated her look with a daring red lipstick, a dark-colored nail polish and a pair of camel-colored Manolo Blahnik sandals. She was joined by other celebrity guests including Adrienne Bailon who opted for a nude top with black embroiders and long black skirt.
In addition to housing Jay-Z's club, the Barclays Center boasts 101 luxury suites, four bars and lounge destinations, and eight retail shops. It will also open its doors to Justin Bieber, Lady GaGa, Rihanna, Green Day and Barbra Streisand for live concerts.
The Hov proudly called the venue "the American dream." He gushed, "That whole thing that you could come here and pull yourself up by the bootstraps, like that whole thing what America has always put up to the world that we represent. I feel that. Yes, I've lived that."
He will officially christen the multi-billion dollar complex in an eight-night live concert starting Friday, September 28.
