Another book on the First Lady will be available for our reading pleasure this fall. “Mrs. O: The Face of Fashion Democracy” (Center Street) is scheduled debut in late October. The author, Mary Tomer, is the founder of another Web site I happen to fancy, “Mrs. O”. The site carefully chronicles the fashion and style of Lady O and this tome promises to offer more of the same, plus rarely before seen photos of Mrs. Obama, interviews with her favorite designers and more.
