Solange Knowles Goes Dotty For David Letterman

Call the doctor - Solange Knowles went completely polka-dotty as she arrived at the Ed Sullivan Theatre for her appearance on The Late Show With David Letterman.


Queen B's sis was actually looking super-cute in the slightly 60s ensemble, which included the main statement piece - that bold-spot long-sleeved coat dress - which she paired with a tan waist belt, T-bar stilettos and megawatt, red-lipped smile.
