On this week's "Sister's Slam Dunk Season 2" episode, the members were required to try on various stage outfits. Somi then revealed a shocking fact regarding I.O.I's "Very Very Very" stage costumes.
The stylists on the show stated that the outfits Somi and the others tried were costumes that were once worn by idols performing on stage. Member Han Chae Young presented Kim Sook a crop top shirt and commented that it looked something a child would wear.
Somi then revealed that during her I.O.I days, she did wear children's clothes for their "Very Very Very" stage outfits. According to Koreaboo, Somi added that the rest of I.O.I actually wore children-sized clothes that were specifically made for each member.
