Thank you to my beautiful green rocking chair for being a model for this display...

Front - note the name on your left... letters on your right. Gamma Gamma, our chapter on the right sleeve. The left sleeve could have your 'number' if you wanted it to. Phi Sigma Sigma nationally frowns on numbers - just to let ya know! (mine is 499 though)
On my collar is a pickle pin and a ketchup pin - from Heinz - go Pittsburgh. When your collar is up we call that 'Elvis' - its a no-no. You look like a nerd. (note that even though you might think we look like nerds in these coats - we dont on our campus - EVERYONE has them - Us, DZ, ZTA, Tri Sigma, DPhiE, TPA, AST... Ask 33girl - ASA had them too. If your sorority was at our school - they'd have em. No one is above 'the jacket'.
Note the way its buttoned too - this is a no-no as well. Always button all buttons
The back. Self explanitory. Your butt patch kinda lets on when you joined. As well as the buttons on the front. If they're both yellow - you're old.
Depending on where you get yours says whether or not you have 'letters' on the back. We dont, Tri Sigma doesnt, ZTA doesnt - DZ used to not. (ZTAs says 'Zetas' Tri Sigma is 'Tri Sigma')
AST, DZ (new), TPA, DPhiE have letters.
Our jackets are yellow, ZTA is powder blue, DZ was pink... now white.
Everyone else has white.
As one of my education professors said:
I always think we only have three sororities... those yellow ones, those blue ones and that big white jacket sorority. They have the most members. There used to be a pink one, but they're gone.
So yea, jackets are a 'status' symbol on campus. Being a colored jacket gets you noticed... "oh I like that yellow sorority...' We also happen to live in a big yellow house with blue letters... coincidence though!
I hope that clues you in on the ways of PA...
