BUR #49128 has been rejected.
create implication undone_bra -> open_bra
undone_bra is defined in the wiki as "A bra that has been unfastened but is still hanging around the wearer's body."
open_bra is defined in the wiki as "A bra that has been opened/unfastened from the front or the back, usually via a clasp, clip or tie between the cups."
Since undone_bra definition says the bra is unfastened, it also satisfies the requirement for open_bra
