What? Don't we all have some prehistoric earrings laying about that we bought whilst in Gstaad 
It's very New York to drop the price of everything one mentions and the vacation attached to it, isn't it? Although I did give the benefit of the doubt that it may have been the way it was presented by the magazine. Also the love for the Financial Times at the end was a bit much. It's a Hearst publication IIRC?
Don't consult me on the feminist viewpoint, I'm a poor excuse of one, but I think that's very valid criticism for both her brand and the Row. They're run by people who already had an in, the right friends, etc. and probably most importantly the cash to fail without any major consequences. Considering the higher than high price points there'd be more admiration if there was a point of access for working women where a job is less choice/hobby and more essential. I'm not talking supermarket prices, or even high street for that matter, but there's a large disparity between the upper end of the high street and brands like these for professional women working up the ladder where dressing appropriately is a very difficult to navigate line. I think it's great that brands like the Row and GH are out there but what they offer should be in easier reach rather than exclusively for women just like them, who have it good and, for the most, always had it good.
Sophie, are you going to do it yourself or see a tailor? If the latter, just take two pairs of shoes with it that you intend to wear with them. There's usually about a 5cm range of difference in height by my best estimation. So low heel/flat to mid heel is doable as is mid-high but flat to high would be difficult to do. Start with flats as you want them as long as possible for the heels but not touching the floor when wearing flats, so get them almost touching the floor, if you can then go up a cm or so with the heels on consider that. But keep in mind if you wash them they will usually lose a bit of length, if they're dry clean only then there's less shrinkage.
