Dressing in dreams serves as a piece of art work and refers a moment when a person dresses themselves in what they hope other people see them as. Some might say that this means adopting certain ideals for oneself, and others may take it to mean dressing nicer than what is skin-deep.
Wearing clothes that you may not feel comfortable in is considered a metaphor for how you see yourself. It often causes problems with embracing personal identity, creating a conundrum for individuals to figure out what they should wear and how to stay true to their personal identity.
