Size four and a half on the Lawns

I saw this discarded shoe (size four and a half) impaled on a post at the western end of The Lawns yesterday and it sparked off a rather brilliant thought process, even if I say so myself. I'm beginning to think there may be some mileage in the idea of tracking down enough discarded women's clothing to make up a whole outfit. I could then open a little boutique called something like Wardrobe Trouvée and sell them on for vast sums of money. If there's a flaw in my plan - and that's a big 'if' there because I think this is a winner - it's the time it might take to find enough stock. It has, after all, been several weeks since I found the other item, this bra. But I might be able to turn this into a selling point. I might be able to convince the sort of vapid halfwit who might shop in such a boutique that their scarcity makes my items that much more valuable. This could be my big moment! Does anyone have Paris Hilton's mobile number?
