The bulk update request #15404 has been approved by @nonamethanks.
create implication frilled_one-piece_swimsuit -> frills
create implication frilled_one-piece_swimsuit -> one-piece_swimsuit
frilled bikini has it's implications, but since the deprecation of frilled_swimsuit the one-piece counterpart still needed to get those
I also think both could get a "ruffled_x" utility alias, since frills is itself aliased to ruffles
