Our Delta Zeta chapter when I was going through pledging made us wear Pin Attire every monday and thursday during the day and on our New Member meetings every sunday night. we had to wear our pledge pin and just below it we had a small pink and green ribbon (like the memorial ribbons) pinned there also. during purity week we replaced them with white ribbons.
most of the sororities at our school did about the same thing with their pledges.
i don't miss wearing heels to class on snowy days!!
