I'm recently back from a (very!) long hiatus and learning my way around the site again. One thing is that I don't have access to any old Pandemic skins in the wardrobe, even though I'm positive I was around for at least 2, if not 3 pandemics and was a zombie each of those times. Is there any way for me to get access to my old skins?

If you had them and then cured, and then got a new one, you cannot get those back.

If you were a zombie at the time of this feature being announced, you could redeem that one, and then go about collecting new strains, or zapper skins.

Aw okay! Thank you for the clarification.
