Highschool research intern attire

I’m a high schooler being a research lab intern this summer at a biochemistry lab, my first day of tomorrow and I have NO IDEA what to wear 😭 I asked about dress code and was told closed toe shoes and pants without holes. BUT I only own two pairs of jeans and the rest of my pants are Brandy Melville Priscilla pants, and every pair of pants I own is wide leg. For shirts I don’t really own any that aren’t uncropped, and if they are then they have graphics on the front… PLS HELPPPEPEP are these even okay to wear?? I don’t want to look unprofessional or something but I only have unprofessional clothes 😭😭
