Words are a waste of time
Monthly collectibles are only available for a short period of time (one month), the evolving items are on sale in the La Victoira throughout the full cycle of their evolutions. After they are no longer on sale they are available on the market place. Evolving items have been known to return in special bundles or prizes fully evolved but this only occurs some time after the evolving item has made a rotation through the cash shop.
You can only wear an item one way, per item slot, per item. So if you want a full look/set of a particular outfit you will need to get multiple of that item.
Destruction is a language everyone understands
