Do they give you a suit for senior pictures?

No, photographers don’t usually provide a suit for senior pictures. Most senior sessions are styled by the senior themselves, so you’ll need to bring your own outfits. If you want a formal look, wearing your own suit—or borrowing one that fits well—is the way to go. A sharp suit can create a classic, polished vibe for part of your session and contrasts nicely with more casual outfits for variety.
