I don't mind the repetition. I don't mind what her pics stand for. I laugh at a lot of them.
It's just that she's not actually that different to the models she's mocking. She's taller than average. She has broad shoulders. She's pretty. She's in proportion and has long legs and slim calves and ankles. She's just 20 years older than a typical model. That's all.
Maybe that's why her posts work, because she's simultaneously like but different to the pictures she recreates.
