The bulk update request #2526 is active.

create implication white_panties (8037) -> white_underwear (20345)
create implication yellow_panties (734) -> yellow_underwear (1988)

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.
