Rugby World Cup 2015, the premier tournament in world rugby, has reached the week mark. Hosted in England for the second time (the 1991 World Cup was shared among five nations, including England) 20 nations are competing at 13 different venues to be crowned king of rugby union.

Talking points from the tournament so far have included the shock victory of Japan over South Africa (fuelled by the RWC's top point-scorer so far, full-back Ayumu Goromaru), the so-called 'Pool of Death' that sees marquee rugby nations England, Wales and Australia all facing each other in the first round, and the highly criticised cover of World In Union by Paloma Faith, which introduces each game on ITV.

With so many fans turning up in England to support their nation, it's no surprise to see many of them hitting the facepaints and costumes in an attempt to stand out. Here's our overview of some of the most colourful and striking fans we've seen at the Rugby World Cup so far.
