K-Pop Concerts Compared to American Concerts?

I love seeing how they group coordinate outfits because it centers around a theme or like kind of preppy or like this or that and then you're like how do they make nine outfits for like one theme using one fabric? It always looks so good. I think maybe overall stage production is like really big for K-pop groups like a huge consideration for them. There's no time for outfit changes or you know like that kind of stuff. So it's definitely more of a like quick 30, 40 minute showcase per group versus like a full blown concert. But what's also fun to watch is the fans who go in their outfits compared to like American concerts. Everyone dresses up for K- pop
