I have a student who is majoring in psychology at university. Every now and then I try to find texts that talk about psychology but that are general enough that I can understand and take part in the conversation.
For a while, I have had a video activity to talk about clothes and dress codes and I finally managed to find an interesting text to match with it (from Forbes, of all places). This lesson can be used with adults to discuss the importance of appearance in a work context but could also be adapted for younger students, mainly those who are about to go to university.
