After a few weeks on campus, I've noticed some patterns. For example, there are always a handful of people who walk into class late. There are also a few people who show up for classes 20 minutes early. The bookstore and cafeterias are always busy. Some people dress up for class every day. Some people dress comfortably every day. Some people don't even have a pencil for class while others have way too many school supplies. Another thing I've noticed are the similarities between many girls on campus when it comes to brands, styles and even school supplies and accessories. These are 14 things that every college girl owns:

1. Birkenstocks

They've made a comeback and they are everywhere. Whether they're the traditional style or the newer style, girls across college campuses are wearing Birkenstocks. Count how many girls in your next class are wearing some.

2. Beaded Bracelets

These Nepal bracelets are popular among girls right now and many stack and mix and match different combinations.

3. Monogrammed Stickers

Girls put these stickers on cars, laptops, water bottles, binders, planners and anything else you could possibly think about. Boring surface? A monogrammed sticker can fix that.

4. Kendra Scott Necklace

These cute little necklaces make the Nike shorts and T-shirts we've worn twice already look presentable. Right?

5. Decorative Planners

Now if we actually use them or not, that's a different story.

6. Longchamps

Because carrying your books in a book bag is so high school.

7. Travel Mugs

Is it coffee? Is it tea? Is it chocolate milk? Who knows? Doesn't matter. Whatever gets us through morning classes.

8. Greek Life Shirts

From bid day to formals, from long sleeved to short sleeved, varying shirts from a plethora of sororities and fraternities walk around campus.

9. Hoop Earrings

Essential to every outfit. Period.

10. Headbands

There are various kinds of headbands with different patterns and styles and girls everywhere are adding them to their everyday hairstyles. Plus it doesn't matter if they match your outfit and that is a big plus.

11. Stackable Rings

Stackable rings are another trend. You can mix and match them and wear them with lots of different outfits and occasions. And they're really cute.

12. Lululemon Shorts

These shorts are really cute and are often paired with oversized, comfortable shirts that cover them up. But trust me, tons of girls are wearing them across campus.

13. Big Sunglasses

What better way to help shield the sun than oversized sunglasses?

14. White Converses

Like Birkenstocks, Converses are also making a comeback. White ones were very popular during the summer and are still a favorite. Girls across campuses are wearing both high top and low top Converse.
