PLEASE HELP!! !I HAVE A PARTY TOMMORROW AND NEED HAIR IDEAS!!! **** 2+STARs FOR ALL ***

please please please help me!!!!

okay so i got my haircut yesterday (i know the plannning sucked but it was the last opening before thanksgiving) anyway, i have a friends bat mitzah tommorow. i really want to look amazing cause she is from my old school (that i went to last year) and my ex-boyfriend and everyone is there and i really want to look good.

Okay so im wearing a deep purple halter dress that has a beaded band right below the boob part. then it kinda flares a little bit.

my hair is medium brown and is like a bob-ish cut that goes to my shoulder. my hair is wavy but i can straighten it.

for the temple service im going to have my hair down - maybe with my bangs pinned to the side.

for the party at night i want my hair up (it gets really frizzy when i jump around) but don't want to just do a ponytail but its too short to do anything that i now of. Any ideas??? i have to look super hot!!1
