I think the whole premise is a bit disingenuous. She works for glossy magazines, and has a certain lifestyle, and wants to justify is as not being incompatible with feminism. And if course it isn't- the one point of hers I do agree with is that we should stop criticising other women for living/ being feminist in the "wrong" way. However, she then went and wrote a book telling other women how to do it her way....
She airily dismisses concerns about the effects of photoshopped models on girls, doesn't care about page 3 or sexist language directed at her (only as long as it's a young hot bloke calling her "babe")- basically she dismisses as irrelevant a lot of things which concern other women, because to acknowledge them would be inconvenient. She is rightly angry about the gender pay gap, measures to restrict abortion, and rape/ sexual assault, and yet doesn't seem to make the connection that these things may be less prevalent if we didn't live in a society where women are objectified, referred to disrespectfully, reduced to a pair of boobs in a newspaper and generally commodified by the industry she works in.
I tried to read this objectively, although I've been troubled by other pieces of journalism she's done- the one justifying constant full body waxing, the one where she says other women are jealous of her because she's thin (admits to ordering food she hates in restaurants to avoid eating) etc. She makes solid but unexceptional points about the major issues she wants us to be outraged about (I mean, no one sane can really argue that the gender pay gap isn't A Bad Thing) but I'm more of the "broken window" school of feminism- I think the combined effect of the small stuff she claims not to care about has an impact on how women are treated in society as a whole.
Overall not a massive fan of the book, although you can't disagree with her stance on the big issues, and I did admire her for talking about her abortions and sexual assault- this is the sort of openness that can only help other women in similar situations.
