Actually, I feel it's a little rubbish to select beauties based on these criteria. Many factors can be added more...like good behaviour, politeness and even some practical tests too........
A world beauty should be a good woman too.......not only skin beauty!!
Please allow some award for physical beauty/ physical charms as well. There are already awards for excellence in various subjects. Nobel Prize is given for excellence in many topics. There are awards for social service and literature . There are awards for films. The sportsmen get so many medals. There are also awards like padma shri, padma bhushan.
So why grudge about awards on physical beauty.
I am also for awards on ugliness.
