Pressing 'A', 'start' or 'x' to custimize will not equip a costume, it will highlight individual pieces but after pressing 'B' to leave the wardrobe tab, it then highlights the original costume and doesn't let you change. Reverting to the original costume after creating a character with the new costume, happens after entering the store of the seamstress with said character.
Expected Results: Not able to change costume and reverting to original costume when in the store of seamstress.
This is a known bug that we were unable to fix upon the release of xbox. There is a work around which I will explain.
Go to the Seamstress (Costume shop) and get to the point of selecting the costume you want to equip. Once the costume is shown on the character us Left Bumber to go back to your list of characters. The costume should now be equipped.
This will be fixed in our never Xbox update!
