Young catholics have a modern sense of pride, or so this t-shirt says. Catholics with Attitude is a UK-based apparel company that has more than doubled its sales this year from last.

Its success is a strong indication that faith-filled clothing is on the rise.

Through word-of-mouth and a global marketing scheme, the group quickly established itself as a niche clothing maker. Now, the company says, it attracts catholics and non-catholics from Puerto Rico to Japan.

Catholics with Attitude was founded in 2006 and was inspired by slogan shirts youngsters sported at past World Youth Days like the one in Cologne.

After all, young people these days are more inclined than ever to express themselves in banners and catch phrases. These are some of the best-selling items for Catholics with Attitude during the summer of 2010.

The company says it is branching out and opening a new sister store just in time for World-Youth Day 2011 in Madrid.
