3. Love Potion No. 9
Maybe there's really something to that whole "sexy costume" thing. In Victorian times, Halloween became the ultimate time to land some love. Divination spells including apple peeling and "reading" egg whites were supposed to reveal the identity of your husband, or help you snag one. Broadly tried a bunch of them out, so put "Love Potion No. 9" on repeat and get to it!
