KARA's Hara is known for her record-breaking running speed, her doll-like features, but also her ant waist!

Hara's tiny waist was first brought to light back in 2009 when KARA performed "Mister", and even after all those years her waist has stayed the same.

On the April 1 airing of SBS' 'One Night of TV Entertainment' Hara came in for an interview. She measured her waist over her thick sweater, and her waist came to be 24 inches. 'One Night' said if you took away the thickness of the sweater, her waist was still 20 inches.�

She said that since her waist was so small, she had been doing some waist exercises to thicken it, but it looks like it hasn't changed!
