Solange Knowles appeared to snub Jay-Z's Carnegie Hall shows earlier this week to attend a Barack Obama fundraiser.

The fashion icon looked amazing in a blue flowing Vera Wang gown with a plunging neckline and showed off her toned legs.

Solange was accompanied by her mother Tina who designed a shirt for the Runway To Win launch. Recently signed to Next Model Management and bagging a column in fashion bible Vogue, Solange thanked fashion desginer Vera for the stunning dress.

"Vera Wang is a true artist. I feel so lucky to be her canvas, if just for this night," she said.
