uniformity

Uniformity is very important during the pledge period. The bothers and sisters want everyone to know who their pledges are, (most of the time). The pledge books will be exactly the same, down to the page. Their clothes will be the same. Some examples are:

Watches on the same wrist.
Pledge pins in the same spot.
Everyone wears hats one day.
Everyone wears the same color clothes one day.
Same color socks.
Pledge books in the same hand.
Can only eat with left or right hand.

Take a look at the pledges on your campus and you will see some of these things, and more.
