I think I have seen a lot of men wearing something like this..ㅋㅋㅋ

Chen, Hwang Minhyun, Ha Sungwoon..

And there's more, but I can't think of them..

-Scoups!!

-My baby has worn the same thing as well..

-Is it the same sweater..???

-Ta-dah!

-Ta-dah!

-Hul.. That wasn't a cardigan?!

-Hul.. I know right.. I've seen that sweater a lot..ㅋㅋㅋㅋ

-Hul.. I've always thought that was a cardigan..ㅋㅋㅋ

-Is it something that Coups wear in Seventeen's M/V for Home..?

-Monsta X's stylists, though..ㅋㅋㅋ They don't give him an inner shirt to wear under the sweater..

-This may sound random but the OP has watched Four Season's M/V. Good taste!!

-Hul.. I have the exactly same sweater!!
