Hello Eleven,
First off, WELCOME TO
KAPPA DELTA!
Nationally, KD has no official policy preventing New Members from wearing Kappa Delta letters. Although it's not specifically mentioned in the policy on hazing, I imagine that preventing New Members from wearing letters might fall into this category. Anything that degrades New Members (and makes them feel "less than") is considered hazing and Kappa Delta has a zero tolerance for hazing.
That said, some chapters might
encourage New Members to wait until they are initiated to wear letters. (Letters are often given to newly initiated members by their big sisters.) This would just be chapter tradition though. No one can prevent you from wearing letters if you choose to do so.
Personally, I think it's nice to wait until after initiation. It makes wearing the letters so much more meaningful.
Ask your VP - Member Education what the tradition is at your chapter. Regardless, you'll have tons of KD t-shirts, buttons, stickers, pens, you-name-it to proudly use during your New Member period and thereafter.
Have fun!!
AOT,
Leslie Anne
