The zekes have their own clothes now: a tee, a hoodie, a flannel shirt, a denim jacket and overalls, all ripped, with rotting skin showing through the tears. Before, they wore the survivors' clothes dyed drab.
The plaid and denim are still recognisable, just faded, so a zeke can look like the neighbour it used to be.
For now it's the broader-built zekes; the slimmer ones get theirs when that art arrives.
