"My body completely changed. I mean, I've worn corsets before but never for this long of a period. Seven months; your body completely changes."

"You can get it on without even lacing or unlacing. By the end I was just snapping it on, snapping it off. It was like second nature. Keira Knightley, who I think has been in more corsets than any other human, told me that there was a whole thing with eating. That you have to time your meals, because otherwise it starts to come up. Definitely. For better or for worse, the corsets kind of put you into the character because it does literally affect everything that you do: Breathing, walking, running, sitting, standing, and definitely eating. Yeah, you do kinda have to time it out because it can not feel so good after lunch."

From an interview with Dakota Fanning in W... where I also learned that "Kim Kardashian Has Officially Introduced the 'Fashion Tail'" and "16 Celebrities Who Prove That 2018 Is Officially the Year of the Bob"

"Officially" seems to be a key word at W. Obviously, there are no officials and no enforcement, so "officially" is a figure of speech.
