i'm a theatre major and going to law school. (well poli sci dbl.)
but i'd say do WHAT YOU LOVE. because in the end, if you hate your major your grades will decline and you'll have a miserable time in college.
i would caution being strictly bfa, fine arts, theatrical arts, because they don't have the "tougher" writing requierments that the social sciences place on students, and this is something that a lot of law schools look for...i mean, you can definitely be a business administration major, and that'll work out perfectly fine for law school...but if u're doing something w/ less rigorous writing classes consider taking classes w/ more of a writing emphasis to show law schools you're capabable.
