Charismatic girls are so magnetic, so having charisma can be a winning point during the final of a beauty contest, and in particular, during the final of Miss Europe Continental.  A participant should be not only beautiful but also with a strong personality, and an easy way to have it is to remove self-doubt, to be sure about your beauty and your importance. Another important way is to radiate a certain kind of vibe that signals kindness and acceptance. The third way to be charismatic is to radiate certaince of success and so also confidence, that is linked to the previous points showed. 

The important thing to understand is that charisma is not a singular thing, it is the mixture of particular features that can be found in a lot of people who spread joy and determination, that can be the best way to live an important final show, such as Miss Europe Continental final.
