binks is right -- borrowing dresses is a great way to find one quick! i let one of my sisters borrow one of my formal dresses for homecoming last year! i hope you have a great time at your formal have have pics to share!!
i'm glad you girls like the jewelry! Believe it or not, I paid $15.50 for this set!!! Sure, I have to pay $8 in shipping because it's coming from another country, but I still think it's a steal considering most formal shops charge $35-$40 for nice looking sets. Pearls are also beautiful for formal! Very glam!
as for asking a boy to formal, i did this for my junior prom and i've been dating the same guy ever since
Basically I just started talking about how excited I was about upcoming prom [in your case, sorority formal!] and i found out he never went to his high school prom. "You've never been to one? It's sooooooo much fun!! You should go with me!!!" hehehe.. i guess i was a little straight-forward.. but hey, it worked didn't it?
