It's only fitting to start this list with a dress that incorporates both the American Old Glory and the UK's Union Jack; after all, a little love to both countries involved in the American Revolution never hurts.
In the middle of promoting her Teenage Dream confection "California Gurls," Katy Perry was spotted in London wearing a rubber dress in support of the 2010 World Cup. The singer wanted to remain neutral in a showdown between America and England. At the time, the former wife of Englishmen Russell Brand tweeted that the dress' shipment was delayed because a passenger passed away on the same flight it was traveling on. However, Perry received the dress on time to celebrate a 1-1 draw as the final score: "EVERYBODY WINS!!! I LIKE THAT! (Plus as an american marrying a englishman... I am DIVIDED)," she said.
