The Knowles sisters stepped out together and in style!

Beyoncé and her younger sister Solange made their first public appearance together since the now-infamous elevator fight between Solange and Bey’s hubby, Jay-Z.

The two were all-smiles and appeared to be in good spirits as they mingled at the Chime for Change One-Year Anniversary event in New York City on Tuesday, where both ladies stunned in low-cut looks.

The "Drunk in Love" singer showed off her coveted curves in a white Gucci jumpsuit, which featured a halter top design, a belted bodice, and a dramatic plunging neckline.

The singer’s baby sis sported a similar cleavage-baring style in a low-cut, tangerine top and crisp, white Gucci trousers.

In addition to being a fashionista, Queen B, who is a Chime for Change co-founder, also showed her philanthropic side when she announced that she would personally donate $500,000 to the charity.

Blake Lively was also in attendance at the event and wowed in a mustard-yellow Gucci dress with leather trim and a keyhole cut-out.

The former "Gossip Girl" star looked positively radiant as she posed for pics with Solange and her superstar sister.
