They are both mothers. They are both singers. And they are both fashionistas. The Knowles sisters may be super-tight and share a lot in common, but their styles seem to be polar opposites -- and nowhere was that more apparent than on the Grammy red carpet on Feb. 10 at the Staples Center in L.A.

Beyonce, 31, chose an elegant Osman Studio jumpsuit featuring a black and white top and slim black pants for the awards show. Her normally curly hair was worn parted in the middle and slicked back in a smooth ponytail. The only spot of color was the bright red on her lips.

Little sis Solange, 26, meanwhile, couldn't have looked more different in a shimmering emerald Ralph & Russo Couture gown paired with bright coral heels. She wore her hair extra-big and curly, and her lips were painted a muted, natural color.
