body makeup for night club

I (17) will be to a night club with my friends (guys as well as girls) next week as the last gathering of the high school gang. We (girls) have planned to go in loose gowns and strip there (we have never been nude before the guy friends). I think it will be better if I be naked but still covered as it will make it even more attractive to guys. I have thought of a butterfly-design vajazzle down there. Will that cover it entirely from the front?

Also I have not got a vajazzle before. Any tips?

And for the rest of my body I wish to get floral design painted (on breasts and hips probably and face so that unknown people dont remember my face). I have not got my body painted before and also never been naked in public. But I am keen to do it this time as all my friends are going naked. Any tips for these?

I think my nipples will pop out and spoil it. Should I use adhesive tapes?
