How To Obtain All Trainer Outfits

Unlike previous Mainstream Pokemon Games, the Trainer Customization this time around can only be done in the form of the outfits your trainer can wear. These outfits will be obtained from various characters throughout the game, and each outfit will contain many articles of clothing within them. Players can then choose to wear the entire outfit, or they can choose to wear certain pieces of each in order to mix and match between all of their outfits.
