But, despite my inner family financial angst, the talk made me think about graduation.
Sometimes I think about how I'm going to graduate in a purple robe and I die a little inside. Sometimes I remember graduating in a red flimsy gown of cheapness and I cringe. Here's a little dedication to the graduation attire of our favorite teen shows.
All graduations are high school unless noted.
Also, I've cataloged where their tassels are in respect to their status as graduates, since we all know there's no consensus on that little detail.
Red
Felicity (High School)

Graduated: Left
Buffy: The Vampire Slayer

in canon. Love Willow's shoes.
Graduated: Left
Roswell

since it's right up my alley (romantic angst + aliens). But I
remembered that their robes were red and they were!
Graduated: Right
Smallville

Clark: Probably hiding in Lex's mansion after killing her boyfriend's mom.
Chloe: At least she won't outshine me in the graduation photos.
Not Graduated: Left
Blue
Dawson's Creek
Graduated: Left (Good in-show continuity!)
One Tree Hill

Not Graduated/Graduated: Right (They didn't move their tassels.)
Black
Gilmore Girls (High School)

and college-prep, so they have cool black robes.
Not Graduated: Left
Gilmore Girls (College)
Wow. I guess despite where I left off with Rory as a petty
criminal living in her grandparents' boathouse,
she did manage to graduate.
Graduated: Left (BAD in-show continuity!)

be blood. Notable also for the different colors for each gender.
Not Graduated: Right
Also, this study further proves how ridiculous the whole tassel thing is and how no one can get it right.
According to the Academic Costume Code and Ceremony Guide, there is no regulation on how to wear your tassel. However, they also state that typically, the tassel is worn to the right until the degree is received; then the tassel is switched to the left. Some say it started for ceremonial reasons; another, more practical reason for it being on the right is because the tassel won't be in front of the graduate's face during photos (as graduates usually cross the stage from house right to house left). That means every one of our graduates is a-okay, even the self-contradicting Gilmore Girls, since it can be assumed that Chilton and Yale have different tassel procedures (but why Chilton would purposefully differ from the Ivies is a far more pertinent question).
So...what color do you want to wear?
