I've made blocks others can import to pkhex that include the unlocked Garchomp and Growlithe outfits as well as both Masks. Just use the previously linked block editing guide and import the blocks to their corresponding sections called "fashion unlocked [blank]" with the type of clothing in the blank (tops, bottoms, and hats are the three relevant pieces contained in the zip). You'll need to import each provided block into the correct section. Also, quick reminder to make a back up first just in case something goes wrong. Hopefully this will help others trying to get the event outfits.
