#meanwhile my housemate from the south (also white) is having major culture shock after moving to washington

[anghraine]

There are a lot of unexplained assumptions going on in the post for sure! But if you do want to know:

The OP is complaining about the (supposed) lack of a distinct cultural "style" appropriate to white people in his region of the USA that could represent the region for the Hatsune Miku redesign meme thing (though I think that's usually a national rather than regional redesign). The problem seems to be that he thinks the cultural signifiers of his region's culture that would be acceptable for use by non-appropriative white people are indistinct from white US American culture in general, which the post seems to assume other white US Americans also feel (many do not, however, hence the ?????? responses).

BTW, if it's not clear, the OP's use of "Washington" is about the state of Washington, the most northwest state in the continental USA (it's on the border with Canada). He's not talking about the national capital of Washington, DC (the latter is what a lot of people often mean by "Washington," but it's thousands of miles/~4000 kilometers away from the state of Washington that the OP is talking about).

The OP's "I don't even like coffee" is a reference to coffee being a huge deal in the larger region that Washington (the state) is in—the Pacific Northwest. So showing Miku wearing merchandise from a local coffeeshop is something that could visually represent PNW culture, but wouldn't speak to the OP personally. The "red leaf shirt" is an example of Washington coffee merchandise and not Canadian national pride, though the OP mentions the coffee thing is so generic that he doesn't know if Red Leaf is actually a national chain. It's not—it's an organic coffee chain that operates mainly in a few middling-sized towns in western Washington, and major population centers even in Washington State tend more towards much bigger chains alongside a lot of niche independent cafes and coffee stands. A lot of people from the PNW who travel elsewhere in the country find the coffee/tea situation pretty dire in most other regions.

The additional unstated subtext of the post is that the Pacific Northwest is very white by US standards, which is why the OP is focusing on the (supposed) lack of a distinct regional culture that hasn't been appropriated from people of color (though I'm not sure he's distinguishing between cultural influences from different groups living in one place and touristy appropriation). Also, the overall population of the larger PNW skews towards some variety of progressive/liberal (though the much more sparsely-populated rural parts tend to be very conservative). So the white liberal we-have-no-culture thing here is actually extremely characteristic of the PNW's majority culture.

For what it's worth, the reality is that there are a ton of cultural stereotypes about white people in the PNW and visual shorthands for them. In addition, I'm honestly not clear why the OP is so fixated on a suitably "white" redesign for Miku in the first place, given that 1) the character was created by a Japanese media company for a Japanese app that imitated the voice of a Japanese actress and was originally marketed to Japanese audiences, and 2) while Washington is heavily white, it has one of the largest Asian diaspora populations in the United States, including a large Japanese-American community. So defaulting to "generic white girl" for "Washington Miku" is rather puzzling in the first place.

the 'miku as your culture' trend has really made me process that white americans don't have SHIT in that department. Like I already knew we didn't right but this has made it so very clear. There's customs and dialects but that's like it. We all dress the same. What would I do for a Washington miku. Put her in a red leaf shirt???? Fucking red leaf the coffee chain? They probably have those in other states. I don't even like coffee
