Help!Prom in 40 days?

I think the makeup you're wearing in the picture looks great. Obviously you're pretty good already. I wouldn't sweat it! As for a dress color...go to JCPenny's or wherever you'd prefer to shop for a prom dress and try on several styles and colors and find what suites you best. Also make sure its what you're comfortable with! There's nothing worse than feeling like you're falling out of a prom dress or any formal attire! Wiggle around in it, dance, stretch, whatever just make sure it's something that will work for you!
