Can confirm this. A part of it is the rapid weight gain - the brain hasn't processed it yet, it will take a light bulb moment for her to actually realise what she looks like, and then she will probably push it away and go eat three cakes to feel better for two minutes.
Despite getting a walker and sizing out of the monthly tarps from mothers', she brought the same sized clothes (or the next size up) from a haul she did roughly a year or so ago where the clothes either fit her as intended or were slightly loose.
There would have been moments of realisation while filming that video, not having clothes fit (probably why she did not want to re-film it) but because everyone told her fashion nova run small, she has an excuse that helps fuel the delusion - i'm not *that* big, they run small in sizing.. *hoovers arbys*
