I won't share the full article as I don't think it's fair on Private Eye to share their content for free. (I'm a subscriber and it's definitely worth buying - only £2 per issue and there's a lot of other good Tattle fodder e.g. Meghan and Harry content)
The review essentially covers a lot of the points already made on this thread i.e. the arguments are flimsy, a lot of the contributors appear to be her media mates, questioning why Pandora presumes she can speak for millennial women, noting that, as Wardrobe Mistress for the Sunday Times, Pandora has possibly contributed to the problems with fast fashion and comparisonitis that she now bemoans.
My favourite bit is probably where the reviewer refers to the book as a collection of "essays" - yes, with quotation marks around "essays" - ouch!
