I've been looking forward to this book for a long time (here's where I first heard about it from Cintra) and it did not disappointment. This is as funny as her still-underrated novel Colors Insulting to Nature and as smart and sharp as her best political writing. I loved it and didn't want it to end! In my mind, the best sections are the ones on Beltway fashion (a must-read!), Utah and the women of the south - in some sections of the book, the integration of the old Critical Shopper columns feels a bit awkward, as they are very funny and full of aphoristic zingers but don't tend to have the depth of some of the newer analysis written specifically for the book - but it is altogether a wonderfully intelligent and funny comment on contemporary American culture.
Here's the Southern Belle bit excerpted at Salon; here's a good interview at WWD.
