Ain't nothin' like celebrity product placement to sell an item - and with a High Street as good as the one in the UK, it's not surprising that celebrities look for affordable fashion fixes, like the rest of us, instead of spending into the thousands on designer. When Kate Middleton sported this patterned tunic from Topshop, which was then pictured in the press, it apparently sold out within the day on the website and in stores too.

If you want a piece of the might-one-day-be-queen's wardrobe, the dress is now only to be found on eBay, unless you're lucky enough to stumble upon one in some out-of-the-way store. Just don't be surprised if it costs well over its original £40 price-tag!
