The phrase “galaxy fashion” is a bit of a misnomer because it’s about more than just fashion. Galaxy fashion can be seen more as a reflection of the culture/social media/technology in our lives that we choose to wear, and not necessarily a reflection of the culture that actually exists. It is a statement that the people who are involved in something and are involved in it for a reason, are part of something bigger than themselves.
The first few moments of a good galaxy fashion film are usually pretty much the best, but the longer the film, the more it feels like a movie.
We see the culture of fashion as a reflection of the people and corporations that are involved in the choice of what we wear. Those same people could be seen as a reflection of the people and corporations that create the culture of fashion itself. It just so happens that in most of our societies, fashion is a sign of status, wealth, power, and prestige, and thus a reflection of these things.
