How to Get All the Items in Your Fashion Case

Travel to Amity Square, which is to the north of Hearthome City in the Sinnoh region. Amity Square is a park where smaller Pokemon are allowed to go for walks with their owner.

Place Pikachu, Shroomish, Skitty, Clefairy, Pachirisu, Psyduck, Torchic, Drifloon, Happiny, Buneary or Jigglypuff at the head of your party and take them for a walk.

Walk two hundred steps with the Pokemon while in Amity Square and then turn to face it. Press the "A" button and your Pokemon will hand over a random item they picked up while walking. These items are either common, rare or very rare items that all go in the fashion case so if you want them all you have to keep walking with different Pokemon until you have them all.

Collect the berries that you find growing on the side of some routes. Travel to Floaroma Town and enter the "Pick a Peck of Colors" flower shop in town. Speak to the woman behind the counter and trade your berries for accessory items. The items all cost different types and amounts of berries, so you might have to make a few trips to the shop to get them all.

Travel to Hearthome City in the Sinnoh region and enter your Pokemon into the "Super Contests." The contests are all held in the contest hall. There are different categories in which you can enter your Pokemon. Win first place in these contests to receive more items for your fashion case.

Speak to all the non-player characters that you encounter in the game world. Some of them give you items for your fashion case, so it is always worthwhile chatting to them. Some items are also dependant on having one of the Gameboy Advance Pokemon carts present in Slot 2 of your DS.

Travel to Veilstone City in the Sinnoh region and speak to the woman that gives massages to Pokemon. She is in the house closest to the gym and by speaking to her once a day you will receive a random item for your fashion case.
