The girl's name is Nerina Orton. She is 22 years old and she is from Birmingham, UK.
She dreams of becoming the owner of the thinnest waist in the world, and she has a good chance.
Now the size of her waist in girth is 40 cm.
The 22-year-old is less than an inch away from breaking the world record of 15 inches held by American Cathie Jung.
Nerina, from Birmingham, even sleeps in her corset and takes it off only to shower.
Nerina, who owns an incredible 78 corsets valued at £15,000, said: 'I may never be able to fit into a 14 inch corset but I love wearing them and I would never be without one
'Wearing a corset makes me feel so feminine and it's a great way for a skinny girl to get some hips.'
'My ribs have moved closer together, so the doctor checks my spine to make sure it hasn't moved out of line or fractured.
'My insides move around a lot too, so the doctor checks that my organs aren't being damaged. I've never had a problem though, apart from feeling a little light-headed.'
But boyfriend of one year Cai Lansdown, who lives with Nerina, worries that she is doing lasting damage to her body.
She said: 'He’s always loosening my corset and saying that if I’m not careful, I’ll cut my liver in half one day.
'One day, I looked in the mirror and realised I looked like a child. It was true, I was wearing age 8–10 children’s clothes. It was a far cry from the hourglass figure of Jessica Rabbit that I desperately wanted.' Nerina suffered from anorexia for a year before she began eating normally again and gained weight.
