I admit I never really understand the design-stealing stories on The Bold & the Beautiful even though they're a cornerstone of the series (and I actually like them, I just have some logic questions, which... well, it's B&B) because one can actually prove things like intellectual property or copyright and generally the design world doesn't run on a "Finders Keepers" system (or a "firsties" system, for that matter) and, even if the fashion world did operate that way, people in these competing design houses are actually friends or even family with each other. And they always just treat it like a spunky coup of some sort.
But you know what? Who cares. Because if it leads to awesome campy bitch-slaps between soapy grande dames?
