• Min Yoongi's measurements: pants 28-29, shirt M (chest 100cm), shoes 265mm.
• pants: tricky because it is between two numbers. I bought him 28 and look for pants that's true to its size. But so far I never saw him wear it so I can't really comment on it.
• Shirt: mostly M but you can go upsize to L or XL since he likes to wear baggy clothes sometimes. He likes both short sleeve or long sleeve (rarely sleeveless). He wear long sleeve mostly for daily life I think. When he's out for schedule he's usually wearing short sleeve (sometimes with long sleeve outer).
• Shoes: sometimes shoes don't have number in between (like only 260/270) depending on how the shoes build is if it's true to its size get 260, if it is on the smaller side get 270. He likes wearing sandals when it's not winter season.
• He's currently using iphone 7(as of February 1st 2017).
• He likes Kumamon, bath bombs, bearbrick, electronics/gadget, and anything related to making music.
• His style: this is just based on my observation, doesn't necessarily reflects his preference. color: white / black / dark shades of colours. Choose something that is "classic" / "clean". Although sometimes he is seen wearing daring colour / pattern / fashion, he generally likes to keep his fashion simple.
• some brands to consider: bape, stussy, rick owens, saint laurent, prada, mastermind japan
• I gave my gift at fansign and no I cant help you pass your gift.
• bighit's address for fan mail / fan gift. They will most likely accept it as long as it's not dangerous items or items that attract tax/gst. You can send through your local post office / ups / fedex / dhl /etc. As far as I know, only massive gift support like the kinda support fansites do that needs permission from Bighit via email (massive gifts support means A LOT of presents), fans who want to send just a few items like for example a couple of tees and accessories can just send it to Bighit without asking for permission. (update per 26 May 2017 they have moved to new office and have officially released the address)

Note: Bighit wont be accepting anymore presents after 31 March 2018, anything received after this date will be returned to sender. They will only accept letters from 1 April 2018 onwards.
