Question

How would someone who is trying to conform use a facade

Answer 1

Well, a facade is a made up impression, story or situation, so somebody trying to conform to society persay is using a facade by pretending to be what they're not. Like say everyone in your class hates oranges, but oranges are your favorite fruit, so you're conforming if you pretend you hate oranges too. 

Answer 2

Let's say that a bunch of persons of said person's interest have a thing for game of thrones. Said person may not like game of thrones, but would do quick research on it and converse with them based upon that. The conformity comes in deep when they are expected to know more about the show after the next episode has been seen because everyone else in that social group will. That person's facade made them somewhat likeable, but they lose a sense of their individuality.
