And if you're the one scrolling through prom ideas on a study break, don't forget to save some ideas for your makeup. While you probably had the prom dress picked out months ago (the big dance also served as a distraction during midterms), it can be easy to forget about the smaller details. But remember: This makeup look will be frozen in time on your parents mantle for the rest of your life (adults are sentimental like that). So, it's important to choose something that you love.
