Given the task definition and input, reply with output. You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.

Person1: Look at these clothes designed by top fashion designer like Versacci , Calvin Klein , and Vivienne Westwood . What do you think of them ?
Person2:Well , they look lovely , but they ' re not very practical . I mean , would you wear that dress to the office or walking down the street ?
Person1: I know what you mean . People would stare at you in amazement if you wore something like that in an everyday situation . I suppose only extravagant rich people wear them at cocktail parties .
Person2:Maybe . I ' m not sure why they have fashion shows like this . Hardly anyone will buy those clothes . The clothes you see are nothing like the ones that ordinary people wear . It seems like a waste of money .
Person1: I think that the designers hold these fashion shows for a few reasons . First , it ' s just like a big party . They can meet each other and network . The other thing is that it is great advertising . All the journalists and photographers are there . Thirdly , it give them a chance to show what they would like to see people wearing .
Person2:You meant it ' s an expression of their fantasies ?
Person1: Yes . I think the designers are saying that these clothes are what they would like to see people wear if those people weren ' t concerned with what other people might think . In a way , the designers are saying ' don ' t worry about what others think . Wear what you like ! ' .
Person2:Very philosophical . I think they design these clothes more for publicity . They try to see who can be the most extreme and outrageous , but still stylish .
Person1: Come on . All this fashion has reminded me that I want to buy some clothes .
