What to wear: As President of the Magical Congress of the United States of America, Seraphina has quite the royal-looking garb. Try to find a fancy embroidered dress or robe. Make sure you get that equally opulent headpiece, and a wand, too!
How to act: Seraphina is President, of course, so you'll have to behave with a certain regal affectation. She's also from Ilvermorny's Horned Serpent house, and her wand is said to attract dark magic. So, you know, you might want to give her a bit of a sinister edge.
