Not really. All my birthdays are just: going out with my 2 bffs in the city, browsing shops, eating pizza and stuff and then going to my place to watch a movie. xD Simple as hell but fun. I never had a sweet 16 (I'm 13) so no idea for your party, but my answer would be keep it simple and invite only your beeeeest friends.
Most of my parties are just going to the de praia, praia and having a bbq but and I havnt had my sweet 16 yet but I think it would be cool to have a rooftop party, or a roof topo, início pool party xp
Be creative and make a big party,like you wish you have it. invite all your friends and you should all come in like,fancy dresses and it's gonna be HUGE! xD ;)
Do what you want but if you want a "HUUUGEE" party, dayyum I wonder how much that's gonna cost. Parties are not really necessary :) Just saying. I usually go shopping and hang out with my ladies, maybe go make some prank calls on the teachers or something xD
elephants, lights, lotsa cake, a big pool, beautiful decor, and cool outfit. if ur a girl i suggest wearin high heels, a flowy dress and maybe a littl makeup. if ur a guy wear a tux
