’So what happens to all those skins you have been collecting in PvP? Well, by now you’ve probably heard about the Wardrobe system, which allows you to collect skins from across the game. When you enter the Heart of The Mists for the first time after the April 2014 Feature Pack goes live, all of the skins you have collected in PvP will unlock in your Wardrobe. There will be a vendor selling basic, level-appropriate weapons and armor for you to apply unlocked skins to. You will be given a one-time allotment of Transmutation Charges based on your rank in PvP so you can restore or change your looks. You can learn more about the Wardrobe system and how it works in our feature announcement blog.
After your PvP skins have been unlocked, they will be removed from your PvP gear locker, and you will have account-wide access to them through the Wardrobe tab in your Hero Panel. As the Wardrobe replaces the gear locker, PvP crafting materials will be removed from the game, so be sure to craft anything you want before the April 15 update.’

The Feature Patch is on April 15th.
Nothing will be ‘changed’, though skins will be unlocked on items in your inventory once you interact with them.
