Mnet Hit the Stage: NCT Ten's Final Performance on Episode 10
Mnet's Hit The Stage has come to a conclusion with episode 10. The final lineup included I.O.I's Chungha, GOT7's Yugeum and more. Above is a picture from Ten's dance team, Prepix's Instagram celebrating the end of the show.
Here's his performance which references his previous dances on the show.
The sweater he is a wearing is from Fay's women F/W 2015 collection. The featured print if Woodstock from Peanuts. Originally priced at around $300. Since it's so out of season, it's totally ok for Ten to sweat into it dancing.
Only sweater I found remotely close to it.
