Hey. So I am an alumna of Longwood. Back in the day, Longwood was a Normal School (a school for women wanting to become teachers). Each woman was required to wear a school uniform of sorts- a long dress (jumper). Some of the women in sororities decided to dye their jumpers with their sorority colors. So, still today, each sorority wears jumpers about once or twice a month (even during the winter). Each woman usually picks out a pattern and has a dress maker in town make the jumper or some moms or grandmothers do it. Colors for each sorority:
ZTA- turquoise
AGD- gingham with green, red and yellow
ASA- red
DZ- pink
Sig Kap- maroon
Tri Sigma- purple
ADPi- blue
AST- green
KD- green top and white bottom
I loved jumper day- they are very comfortable!

Longwood has tons of quirky traditions, all of which I loved! Hope this clears things up!
