Michelle Obama looked stunning in a strapless Oscar de la Renta gown for the 38th Annual Kennedy Center Honors Sunday. The first lady of the U.S. showed off her cleavage in the blue and black confection. The floor-sweeping number had floral and leaf patterns all over in blue.

The gown is from the American label’s fall 2014 collection. It is from the designer’s ready-to-wear collection Look 54. The gown featured a sweetheart neckline and a fitted bodice.

The strapless number had a voluminous skirt in black tulle. The blue color of the gown added a festive touch to her look. Also, the striking blue color teamed up well with the black skirt.

Michelle’s gown drew attention to her tiny waist and her toned arms. She paired her ensemble with drop statement earrings. Her hair was kept in a slicked back do. She completed her look in a pair of black high heels.

The 51-year-old mother accessorized with two chunky rings. For her make-up, she opted for pink lip gloss and smoky eye make-up with lots of mascara, eyeliner and a hint of eyeshadow.

President Barack Obama, complimented his wife in a custom tuxedo. He looked dapper in the all-black outfit that he paired with a crisp white shirt and matching pocket square. Obama completed his look in a black bowtie and black lace-up shoes.

The Obamas honored five of the six honorees, Carole King, Cicely Tyson, Rita Moreno, George Lucas and conductor Seiji Ozawa. The Eagles, have postponed their participation until 2016 due to singer Glenn Frey’s ill health.

“Tonight, we honor five artists who helped tell the story of the first American century through music, theater, and film -– and by doing so, helped to shape it, helped to inspire it, helped to fortify our best instincts about ourselves,” Obama said introducing the honorees to a star studded audience.

He had a busy day and made at least three wardrobe changes Sunday night. Between the reception and the event at the Kennedy Center, Obama changed into a dark business suit. He delivered the 13-minute speech, addressing the recent San Bernardino mass shooting in a national televised address.

The 38th Annual Kennedy Center Honors will be broadcast on the CBS Network on Dec. 29.
