Personally I think the show is discredited by all the flashy clothing worn by the competitors. Viewers and voters are distracted by the bling, and in many cases by the overt nationalism shown by some of the clothing on display.
It would be better if the competitors displayed in the nude, and without their nationality being mentioned until the end. That way any unwanted "national" sentiment is removed, and any visual distraction afforded by the clothing is removed.
Naked performances - much fairer for all
