Michelle Obama Glows in a Sunny Yellow Dress at the White House.[Photos].#Flotusslays

A sleeveless dress never looked so good. First Lady Michelle Obama andPresident Barack Obama welcomed the Singapore Prime Minister Lee Hsien Loong and his wife Ho Ching to the White House today, and the FLOTUS definitely brought her style A-game to the event.

For the historic occasion, the 52-year-old wowed in a brilliant yellow Naeem Khan dress that featured intricate floral appliqué, a sleeveless halter-style neckline, and semi-sheer hemline. She paired the winning frock with a matching leather belt, nude heeled sandals, and emerald green statement earrings. Michelle has been all about rocking vibrant hues as of late. This colorful and summer-ready ensemble follows the stunning royal blue number that she wore last week while giving an impassioned speech at the Democratic National Convention.

President Obama and the First Lady will host a state dinner in Prime Minister of Singapore's honor tonight.
