On the topic of BAPE, In my experience, it had a huge influence in South East Asia. Growing up in Brunei, the coolest thing you could have on your shirt is some variant of Baby Milo (from BAPE).
If you had one of these BAPE tees, you grab every other teen's attention and it basically signifies how 'hip' you are. Every time anyone saw one of those tees, they'd get asked where they bought it from because no one knew! There was never a straight answer. It was always, "oh, my mom bought it for me." or something along the lines that of buying it while travelling abroad. Just imagine seeing supreme everywhere but not knowing where to get it.
There was just something so cool about Baby Milo to the people in my country. Girls LOVED it because it was cute, guys loved it because it was hip/cool. It appealed to every age, gender and ethnicity there. Baby Milo became so popular that you'd get small companies or whatever making Baby Milo stickers which looked terrible to sell out to people, a lot of people would have it as their display picture on friendster or some kind of wallpaper. There was even a company who parodied the shirt and wrote 'FAPE' instead of 'BAPE'. We called it the Fake Ape, and it sold well for a bit then died quickly because having 'FAPE' on your chest is all kinds of wrong.
Of course, trends die and people move on. BAPE still exists now but on a much smaller scale, probably people rocking their 5 or more, years old tshirt.
Woah. Can't believe I remembered all that. Now i feel like i should get a BAPE tee before i return to Brunei in summer and maybe revive the Baby Milo trend again.
