The bulk update request #2526 is active.

create implication white_panties (8046) -> white_underwear (20363)
create implication yellow_panties (735) -> yellow_underwear (1993)

Reason: All the other colours are already implied to (color)_underwear but somehow these two were missed.

EDIT: The bulk update request #2526 (forum #335430) has been approved by @bitWolfy.
