Fab chick Solange Knowles hit the 1's and 2's at last night's Museum of Modern Art's (MoMA) Garden Party in NYC.  And she kept with the garden theme by rocking a green and white floral skirt that is actually half hot pant with the matching coat all by designer Flaminia Saccucci.  She always gets it right.

The lovely pics of her, Santigold, and designer Rachel Roy inside...

MoMA's Party in the Garden, an annual fundraiser to benefit the museum's general operating fund, went down inside the Abby Aldrich Rockefeller Sculpture Garden last night:

DJ/Singer/Songwriter Solange let her creative genius flow in this cute garden party look.  Loves it all--especially that pebble print box clutch.

Solo kept the party rocking all night.

And she exchanged tweets with her followers:

Your right! Ha!! “@richardfleming: I told @solangeknowles to throw em up but I think I confused her! She's rockin MoMa

Meanwhile, Roc Nation artist Santigold hit up the event and performed in this blue Marni Spring 2012 party dress:

She is set to perform at her boss Jay-Z's "Made In America" festival in Philly Labor Day weekend.

And designer Rachel Roy--who Solange rocks often--made her way to the event.   The party raised $3.8 million for MoMA!
