Teens
Skinny jeans (practically everyone in my highschool has at least one pair.)
Girls wear dresses above the knee but a lot just wear tee shirts and jeans.
Sneakers with nike logos on them, and converse (Mostly guys wear nikes)
A lot of girls have things called fly-aways which are like sweaters but with out buttons.
Sweatshirts are a must. (both guys and girls)
Guys sometimes where dog tags (Military necklaces)
A lot of guys wear extra large tee shirts.
Flat brimmed hats or baseball hats are owned by all guys.
Large earrings and chunky jewelery are what lots of girls wear.
Adults
Jeans, tee shirts, button downs sneakers.
Hope I helped! :)
