What accessories should I add?

I'm getting slimed (covered in nickelodeon green slime) tommorrow for a charity fundraiser. Everyone I asked including friends and people on here said i should get dressed up to get slimed because it would be funnier, so I'm going to wear my white dress from prom with silver heels. Do you have any advice for accessories I should wear to complement that to make the outfit more stylish and look funnier when I get slimed? Should I get slimed with my purse to make it look like I didnt expect it?
