What are your world's current fashion trends?

Fashion is always changing. Tell me about what new trends are popular in your world, and any relevant context.

Maybe a certain celebrity popularized a new hairstyle, or a new religion has more people donning robes? Are there new flying boots causing an increase in injuries among teens? Has the newer generation decided to do away with their grandparents' horn decorations as the social statuses they signify become less important to society?
