It seems Jungkook is around 178cm tall and weighs about 72.3kg. I'm not a hardcore fan, so this information is from the internet... If you're trying to get a similar look, I think: XL for people around 180cm L for people around 170cm M for people around 160cm would be a good recommendation. I hope this helps. By the way, there seem to be fakes being sold for under 10,000 (currency unspecified), but I recommend the authentic product. The line of the clothing will definitely be different when you wear it, just based on the different materials.
