Like the rest of the Crystal City, the fashion is a mix of new and old; technology versus tradition. It is somewhat a mix of modern Japanese street style and 1980's Western style. It is usually a bit zany and outlandish. Candy colors mixed with edgy, survivalist pieces. Think VERY Tank Girl.
At school, students are required to wear a uniform at all times. However, I encourage you to make your Sailor Scout attire as unique and outrageous as possible. It's more fun that way.
