Twiggy
I was watching the Twiggy episode recently (season 1) and I found it so refreshing to see a celebrity who had imperfect skin. It really struck me with Twiggy because she was a 27 year old international model but you could see the blemishes on her skin during her first song.
Nowadays everyone is botoxed so much that they no longer look real. This fear of imperfection can't be healthy!
