On a new episode of Mnet's 'Standby IOI' on April 29, the members could be seen enjoying a party!
Member Kim Se Jung said to the camera during this, "I am confident in eating. I want to film a chicken CF. I lost too much weight. I've become [size] 33 instead of 44 (which is about XXS in U.S.). I lost 4 kg (~ 9 lbs)."
Might be easier for her to find clothes in the children's section!
