So the Duchess of Cambridge wore a £150 dress from Whistles for the London 2012 Olympic closing ceremony last night. It turns out our Kate ‘recycled’ the Bella dress (read ‘wore it again, like any sensible person’) after its first outing at the Diamond Jubilee Concert in June.

Would a dress worn by any other celebrity be as desirable? Kate Middleton’s largely British High Street wardrobe has seen many a woman come over a bit Single White Female, rushing out to buy her latest Reiss/Whistles/French Connection number and send store profits through the roof.

Lucky for us, the Bella dress is still available, albeit in a different colourway, in Whistles stores and on the website.

We’re sure it’s splendid for the ecomony, but is it doing anything for our street cred to turn up to social occasions looking like a photofit of the princess?

Maybe that’s the crux of it; perhaps the woman who buys a dress after seeing a royal in it is just indulging her princess fantasies. You know, regressing back to when we were eight and dreamed of looking like Cinderella and marrying Prince Charming.

After all, Disney has launched its own line of wedding dresses, including a voluminous strapless ‘Cinderella’ option ‘fit for a princess’.

Preferably, we’re all totally over that fantasy by now, and we’re simply buying up Whistles’ rails because the duchess looks nice, and when you see a woman looking nice in a dress, you tend to buy the dress so you can look nice in it too.

Question is, will you be buying it?
