Beyonce And Solange Knowles Prove Sisters Who Match Their Outfits Aren't Mad At Each Other

Beyonce opted for 1970s-style tailoring in the sexiest white jumpsuit you've ever seen for Chime for Change's one year anniversary party in New York. However, more interesting than her outfit was her guest - little sister Solange.

Yes, last night was the Knowles' first public appearance together since that elevator meltdown at the Met Gala (Solange made her solo red carpet comeback at the CFDA Awards earlier this week).

And just in case you were wondering, there's no bad blood here. They even co-ordinated their looks for the event. And their nail polish.

Solange wore an unbuttoned orange shirt with slit detailing on the sleeves, the most sophisticated white trousers (tailoring is everything) and carried a boxy gold clutch.

When they weren't arm-in-arm for photos, the sisters were chatting with Blake Lively who was pure 1960s siren in a plunging yellow mini dress and glittery gold stilettos.

The event - hosted by Gucci Creative Director Frida Giannini and T Magazine Editor-In-Chief Deborah Needleman - wasn't just about fashion. Women's Wear Daily tweeted that Bey had been more-than generous on the donation front too.

Chime for Change raises money and awareness for projects promoting Education, Health and Justice for girls and women, so it's no wonder Beyonce is backing the charity
