Each culture has different thoughts on what "fashion" is.
Most cultures want to look nice and may have a different idea on what looks appealing.
We, as Americans, and Iowans change our idea of "fashion" everytime something new comes along.
Even within our cultures, everyone has different ideas of what clothes or styles look good.
Normally, Iowans wear typical clothing.
Shirt, shoes, pants, etc.
Many people wear sweatshirts, and for some maybe a baseball cap.
Sunglasses are very popular in our culture, the reason why is because when it gets sunny it gets SUNNY.
Overall, when it comes to clothing it's really up to your personal preference.
