In Alpha Gamma Delta, it is an Initiation requirement that you must order your Badge at that time.
When I pledged in the dino age and b/c the chapter was only 2.5 years old lol, we all ordered the all pearl Badge with Chapter guard. These days almost everyone orders the plain (no pearl Badge) and no Chapter Guard.
I know Badges can be expensive but I wish they would at least order the Chapter Guard.
A few years ago, I ordered a plain Badge, which I have to "lend" to a collegiate every now and then when she forgets hers, lol.
Congratulations on your Badge!!
