Is Madonna a trendsetter or a trendspreader?

Yesterday Madonna was performing in Moscow, at stadium Luzhniki and whatever media are broadcasting I didn’t witness any fervent orthodox demonstration, it might due to the huge number of soldiers and policemen devoted to the security.
The music and the show were great, even though the Kabbalah inspiration is far more visible than her previous tour, damaging the show. I expected great motion design on the background screens but they displayed a lot of too-explicit anti-war clichés (Bush’s diatribes, poor Africans…) while the warwear defile was, according to me, more pertinent and much more performance-focused.
Well in fact in this post I’d like to deal with two weak signals, not so weak actually, which can help in fashion prospective. The secret is Madonna doesn’t do the fashion but follows it, much earlier than mainstream I must admit, but anyway the both trends I am to develop could be witnessed before.
Confessions Tour starts with a horse-playing theme. However the polo was yet the new golf: Citizen K and Diesel both sponsor the Open de France de Polo and Ralph Lauren has turned hype since they had made the logo bigger, so equitation uniform should hit the street soon.
Second trend is about wearing only the sleeves of a t-shirt and having the body of t-shirt behind the neck. Madonna didn’t dress this way, only some dancers of her crew. Nevertheless now that perfect abdominals only request reading a book, more and more men wanting ROI from sport club membership show off their body. Now you know how to do it trendily.
