The clothing store in Love Nikki, is one of the easiest ways to obtain clothes. You will only need gold and diamonds. A lot of items in the store are used for crafting and stages, but there are a few that are used for evolving. The price is lowered for V's and if you are not a V, it is okay, because you earn enough currency to buy most items. MOST of the items that are part of a suit, are in the Special or Rare categories.
