I have a Nicole Miller Rosewood shower curtain, but found out accessories have been discontinued.?

I recently bought a Nicole Miller Rosewood shower curtain from Bed, Bath, and Beyond, but found they have discontinued the item and no longer sell the matching accessories. The shower curtain is white with a black paisley/vine design(impossible to match) and a large black band at the bottom. I am looking for some plain white towels with a large black band at the bottom. I've looked everywhere. Any ideas on where to find some?
