Beyoncé and Solange Are All Smiles at Gucci's Chime for Change Event

Bey reportedly donated $500,000 at the event!

Beyoncé sure knows how to sexify a jumpsuit.

The stunning celeb attended the Chime for Change one-year anniversary event hosted by Gucci Creative Director Frida Giannini and T Magazine editor-in-chief Deborah Needleman at Gucci Fifth Avenue in New York City, and looked absolutely gorgeous in a white jumpsuit with a plunging neckline that helped flaunt her cleavage.

Bey was joined by her younger sister Solange Knowles, who also gave a peek at her naughty pillows while wearing loose, bright orange blouse that was unbuttoned to her midriff and white pants.

Both of the Knowles sisters seemed to be in good spirits, flashing their big smiles throughout the night. Queen B was photographed chatting it up with Blake Lively, and Solange even hit the deejay booth!

In fact, Bey reportedly donated a hefty amount of cash toward the good cause. "At the Gucci Chime for Change event in NYC, Beyoncé just announced a personal donation of $500,000 to the charity," Women's Wear Daily tweeted.

According to the website, Chime for Change is a global campaign that helps strengthen and unite the voices of women all around the world.

"We focus on using innovative approaches to raise funds and awareness for projects promoting Education, Health and Justice for girls and women. To date, we've rallied support through a global concert event, a series of short documentary films, a range of technology-driven solutions, and by highlighting the stories of girls and women everywhere who want to see change.  With your help, we've funded more than 300 projects in nearly 80 countries.  And we're just getting started…," the website states.

Beyoncé is a co-founder, along with Giannini and Salma Hayek.
