3. Michele Koebke- 16 inches waistMichele Kobke has shrunk her waist from 25 inches (64 cm) to just 16 inches (40 cm) by wearing a corset every day for three years - even while sleeping. Despite having a waist smaller than most catwalk models, the slim German says that she hopes to whittle her waist down to a shocking 14 inches (38 cm).
Wearing a corset has affected her health terribly as she already struggles to stand up without her corset thanks to atrophied muscles in her back and stomach. Her stomach is so constricted that she can't eat a normal meal; instead, she eats up to 10 small meals a day.
