Pinky Paradise is fantastic for cosplay contacts! They have metric TONS of lenses available. Although I haven't purchased any myself, I've heard that they are reliable, safe, and they do have real customer pictures.
Here is a contact that is a nice yellow color like your character and has a thick black band: http://www.pinkyparadise.com/Princes...-p/f24-f33.htm
There are many others that you can see here
However, as far as actual cat-eye contacts with the vertical slits, I can't find any yellow ones that have black bands around the outside. My suggestion is that this detail is pretty small, and if the black bands are more important to you, just pick out some pretty yellow contacts and wear those! However, perhaps someone else on the forum will be able to find contacts that fit your exact description.

I'm a Florida graduate student who must choose between following the heart (which wears a flower crown and carries a basket of cookies while skipping along a beach) or following the brain (which wears a graduation cap and carries a clean bill of no student loan debt). So far, I choose to follow both.
