Black white and silver themed party. decoration ideas please? - sprite sheet food

Hello guys =)
in organizing a 18 from a friend, and it will be filled with white and silver ... but also the black dress code.
Ive had the ideas of white candles and a freezing of money on the ground, pure white with silver on top of the wall (btw is outdoors), white tablecloths, a few lamps. Theres two things fire with chairs around them.
Food ideas include tzatziki sauce, Sakata, Piña Colada, Sprite, Diet Coke (cans) are silver, black (double silver cans are lol). and the cake with silver beads biscuits in a pyramid, white stacked a small thing.
other ideas please? or I missed something?
No balloons or banners please!
Thank you!
