In the Japanese versions of Ruby and Sapphire, if you visit the man in Pokemon Fan Club in Slateport City that is sitting on the couch, he will give you a colored Scarf to Pokemon with maxed Contest stats: Red for Cool, Green for Smart, Yellow for Tough, and so on. Strangely, if you have a Pokemon with max Smart stat in the Japanese versions and speak with the man, you will get a Green Scarf, and if you do it again you'll also get a Yellow Scarf - regardless of the Pokemon's Tough stat.
