Designer Rubin Singer, who recently dressed Beyoncé for a private concert in Las Vegas on New Year’s Eve, tells Glamour that Beyoncé and Solange Knowles are “the only celebrities that always dry clean and send clothes back in a box, with a hand-written thank you note. They are true ladies.” That’s lovely of them. Now just imagine all those other celebrities returning dirty, stinky, noteless garments in an old grocery bag months later, if at all.
