The Fashion Case (Japanese: アクセサリーいれ Accessory Container) is a key item in the Generation IV Pokémon games which holds Accessories and Backdrops. There are several different sections for these Accessories: Fluffs, Pebbles and Boulders, Scales, Feathers, Facial Hair, Natural, Flowers, Specs, Misc, Contest prizes, among others. Additionally, there are fifteen Backdrops.
In Diamond, Pearl, and Platinum, it can be obtained in Jubilife City after defeating two Galactic Grunts with the help of Lucas/Dawn, with two Backdrops and a few Accessories to start with. In HeartGold and SoulSilver, Ethan/Lyra will give it to the player when first entering the Goldenrod Tunnel.
In Diamond, Pearl, and Platinum, extra Accessories can be picked up by Pokémon in Amity Square, won in Super Contests, found by the Massage Girl in Veilstone City, traded for Berries at the Pick a Peck of Colors Flower Shop in Floaroma Town, or given by various NPCs. In HeartGold and SoulSilver, random Accessories are picked up at random by the Pokémon leading the party while walking, won in the Accessory drawing in the Goldenrod Tunnel, or given by various NPCs. However, in HeartGold and SoulSilver they serve no purpose other than taking photos in Goldenrod Tunnel.
