So much for a simple Nets t-shirt! Beyonce wore a luxe outfit while sitting courtside at the Brooklyn Nets game at the Barclays Center on Monday, Feb. 3.

For the Nets-Philadelphia 76ers match-up, Bey, who sat with her husband Jay Z and Super Bowl champion quarterback Russell Wilson, kept warm and looked oh-so-cool in a leather-paneled tartan jacket by Karl Lagerfeld that costs $630. She paired the luxe outerwear with dark jeans and black Prada boots.

To finish her look, the "Drunk in Love" singer, 32, wore an adorable Eugenia Kim pom pom hat with a price tag of $165.

The casual outfit was a change from the diva's more glam side, which has made headlines in recent weeks. Just one week before, Beyonce wore a sheer white gown by Michael Costello to the Grammys, where she also performed onstage in a skin-baring leotard. On Saturday, Feb. 1, Blue Ivy's mom flaunted her famous figure at a pre-Super Bowl bash in NYC by wearing a black, sheer-paneled gown by Roberto Cavalli.
