Only in America can an A-list baseball player be seen exiting a strip club, and hence add over $70 million in market cap to a fashion company's stock value.
On the morning of May 30th, copies of the New York Post hit the stands showing a large photograph of A-Rod exiting a strip club with an unknown blond woman (not his wife). The photo apparently shows A-Rod wearing a pair of True Religion jeans, to which Wall Street interpreted as yet another celebrity endorsement for the product.
So A-Rod wears them, Fergie sings about them, and you pretty much need their salaries to afford a pair. Personally, I just can't stomach paying more than 30-40 bucks for a pair of jeans. Perhaps I take pride in dressing hip for half price.
