You should get some silver and white party supplies balloons, decorations. you should get some champagne cups that are silver or white-ish. but plastic ones? from any party supply store. you could also buy silver spray paint and spray paint your friend’s names on a piece of cardboard and place it at their seats in the restaurant (spray paint outside haha). I don’t know if you parents would let you but to order one bottle of champagne to your hotel room. I live in France so the drinking age is 16… but I’m not sure for you.

you should also have gift bags, i know that sounds lame but if you fill it with a pair of earings, a tiara, fake diamond things.

you should wear a tiara the whole night 🙂
