I'm not against owning any of these things (trust me I'm a fashion major and would die to own some vintage Chanel) but I would just like to second the notion of those who have posted that these things aren't nessisary and not the real idea behind a soroity. Speaking as a converted anti-soroity girl who was won over by the acceptance and open-heartedness of the Chi-O's the only true nessessity is...
Sisterhood:
from simply always having someone to walk to class with to the best friends who will be there to listen to you gush over your new guy when you come home at 4 AM to the thrill of meeting a sister from another school and the instant connection.
this is why I joined a soroity and all I really need.
(though the diamonds and pearls ect. would be nice)
