You have to hand it to Marc Jacobs: he's nothing if not inclusive. Who else, for instance, would think to design a dress specifically for people with one arm significantly longer than the other?
Oh no, wait, our mistake: it doesn't actually have one arm longer the other. It just LOOKS like it does:
And now that we see how it REALLY works, we can see our first assessment was wrong: this is clearly one of the new robes for the Hogwarts Quidditch team. As we said: inclusive! Thinks of everything! Charges through the nose for it too, apparently, because this sports-shirt/dress was originally priced at £935, before being reduced to a still eye-wateringly expensive £561. Tempted?
