* Individual school culture: Some schools might have a more subtly defined dress code than others, even without an official uniform. One school might lean towards a more preppy style, while another might be more casual.
* Individual student style: Like anywhere, students express themselves through clothing. Expect a wide range of styles, from athletic wear to more trendy outfits.
* Weather: Portland experiences all four seasons, so clothing choices will vary greatly depending on the time of year. Expect to see everything from winter coats and boots to shorts and t-shirts throughout the year.
* School dress codes: Each school will likely have a dress code outlining restrictions on things like inappropriate clothing (revealing attire, gang-related symbols, etc.).
In short, you'll see a diverse range of clothing styles reflecting the typical middle school trends and the season, all within the parameters of each individual school's dress code.
