They work, in theory, and would not appear different, but they have not been discovered, and it not even predicted that there are some areas of the universe in which antimatter prevailed after the Big Bang (thought to be quite uniform in early history of universe).

Fundamentally antimatter stars would not look different from Earth so long as they were in an antimatter-dominated region. The problem with this is that this region would have to eventually border a matter region an at that interface the would be a massive and very characteristic emission of energy (light) as the matter and antimatter annihilated (which we could easily observe). This is why we don't think that there are any hidden pockets of antimatter in the universe.

Because of a subtle breaking of a symmetry in physics, matter won out over antimatter. There's none predicted to be floating around.
