1) i have 2 pins. my grandmother's crown pearl (that's what they all got at her chapter) which she passed to me at my initiation, and my own plain scrolled edge one. i wear the pearl one.
2)my chapter all has the same style. we're not given an option, though i think if someone wanted to get a more fancy one they could.
3) no i'm a poor college student
4) i personally like the pearl one! it's just classy. . .
