Closet Swap is not compatible with all items. While it will allow you to save with certain items, others may not work. It is best to save items one-at-a-time to avoid losing an entire outfit.

As well, make sure you have enough points to purchase the item (if it isn't free). Using Closet Swap allows you buy items that are no longer located in the Shop. It will not be able to save if you do not have enough points for the item(s).
