I love bright shirts (including yellow)!
For my bid day, we got purple shirts that say "Alpha Sigma Tau" in white in a cute font (hearts in the letters).
This year's bid day, we got pink shirts that say "AST" in Greek on the front and on the back have a brick chimney outline design with the national founders' names on the bricks. Below that, it says, "Alpha Sigma Tau - laying the foundation for the best chapter in our lives!" (Which works out great, since we will now be initiated this April!)
Speaking of AST shirts, I am in a red one right now with green letters with ladybugs and white daisies on them (the matte is marigold). Have a great night / spring break everyone!!! Tau love to all!
