On the other hand, if you consider just how conservative tango is in this part of the world... It's a big dose of star power and other factors.
I could hardly give a bat's fart about people telling me what to wear at a milonga. I've danced long enough that I know I'm at my best when I'm most comfortable. A friend just got back from an event in Shanghai, for example, and he told me explicitly that the moment he walked in to the first milonga of that event, he felt uncomfortable. Everything was too stiff, formal, ritualised even, and the people were overwhelmingly into the Mundial style. So he spent the rest of his time having more fun in the local milongas instead.
Insanity! What is this ridiculous habit of isolating and elevating tango that happens so much here in Asia? How the hell do you even dance milonga properly then? It's not milonga if it's not grounded and dirty! Right now, in many, many places, tango is a dance primarily for an affluent middle class, and it shows. Oh, it shows. Their affectations and pretensions to high society reveal their true colours.
South Korea isn't so bad, because I've personally danced with dancers from Seoul who felt amazing and stayed in the embrace the whole time.
