To wear accessories, simply go to the main menu and select "Inventory". Pick "Accessories", and select the accessory you'd like to wear. There are various accessories-some you can buy, some you can find by barking at other creatures, and some you can create using materials. You can also go to different stores in each town and find a shop where they sell accessories, and you can buy accessories to make different accessories out of them using the Accessory Creater thing in Malshige's Shop in Pupsville. You can also go to other areas, and go to their accesory shop. They will sell different accessories that no other shop has.
