Korean Formal Dress

[gillkid]

I hope I got the pics uploaded correctly. I come across this shirt and cant seem to find out what it is. Hope you guys can help. Some things of note, this guy had antique chemical equipment as well. He and all his family was Korean. The only thing I didnt post a pic of was the buttons. All patches and marking are shown in the pics.
