Hi - I draped fabric over mine, gathered it firmy in back and
stitched (or pinned) it in place. Just check the front before
securing the back so there’s no gathers or folds. I notice also Rio
is selling elastic-backed covers, but I don’t like how much of the
original bust shows through in the back. Either way, you can
customize your color/texture and just replace the cover if it gets
dirty or worn.
