i normally have big birthday parties compared to my friends about 15 or so girls come over and then have a slumber party. We normally stay up all night till the morning and my past birthday parties have been things from; hollywood dinner and red carpet, spa themed, jonas brothers themed haha, and last year we had a splatter paint themed. SInce this year it will be my sweet 16 i want to have a big fun birthday but not as huge as the ones on mtv like i dont expect a car or having my party cost 1000 dollars. But i was wondering what were themes or items that i should have at my party and like things that should be done there? Please let me know
Thanks
