A faux pas, or a new trend?

On a more frivolous note -
a couple of weeks ago I attended a big tango event and apart from the fun of getting to dance with people from all around the world I also had the pleasure of watching the show of the teachers, among whom there were some of the greatest couples of both Argentine and international renown. The performances were great, I enjoyed them so much! The last time I had seen these people dance was months ago at the milongas of Buenos Aires, either performing or dancing socially, but here such treats are harder to come by, so of course one appreciates them more;)
Anyhow, there was one aspect of the performances which at first seemed harmlessly amusing but became quite bewildering as the shows went on and I realized this was a recurring feature: in three out of five couples we got to see a lot of the woman´s knickers during the dance - and I don´t mean a glimpse here and there during a particularly high boleo. The fourth couple broke the pattern because nuevo dancers rarely wear skirts, and the fifth one were two men who both wore trousers.
With the first couple it was, by the look of it, a case of a very beautiful dress of an unfortunate cut and material with a very high slit which was to show off the girl´s thigh but, as it slid around her body during the dance, ended up showing off a completely different part of her body, luckily covered by her knickers. Oh well.. that can happen. But as the performances continued, what with high slits and ultra short skirts, the trend became clear.
I certainly don´t mean to criticize the waning morals of our age:) I just think the matter is noteworthy and cannot be waved aside as coincidence. It might even be a new trend in tango fashion, so I point it out here for those of you who want to be up to date;)

BTW, seeing as Eugenia was the one nuevo dancer who wore wide pants and did not show her knickers, I can name her without compromising her, just to say that she is really incredible; the chica is so graceful you can´t take your eyes off her when she´s on the dancefloor, regardless of whether you like tango nuevo or not. I don´t particularly like her style of dancing, but her moves are so full of grace, it is simply a pleasure to watch. And I really liked her with Ezequiel, they have a lovely connection and on the dancefloor they are just two beautiful people.
