In Step 2 Cove has two hairstyles, two shirts, two glasses + no glasses option, one necklace + no necklace option. Those are all possible in the demo. Having various combinations of the different hairs, shirts, and accessories are probably what's being counted as four different looks. But it is right that there are only two shirts (the blue one and red one). He also has two pants, two left bracelets + no left bracelet option, and 1 right bracelet + no right bracelet option. Those can't be seen in the current demo, though.
