Since this is prom, I say do something special. A smokey eye, in my opinion, is not the best bet for a hot pink dress. I would say do a light neutral eye but with lots of eyelashes. Not crazy porn star lashes or anything, just thick, full lashes maybe with a few individual falsies in the outer corners. Then do some contouring with a bronzer which will look great with the colour of the dress. Use a light peachy pink blush (my fave will always be NARS Orgasm). Then put all the focus on the lips with a hot pink gloss!! I love NARS Hot-Wired, or MAC Pink Poodle. Have fun with it!
