What should you know before booking your first fashion photoshoot?

Trying to book a fashion photoshoot for the first time and realizing it’s not as straightforward as I thought. I assumed you just find a photographer, share a moodboard, and that’s it, but now it feels like there are a lot of moving parts behind the scenes. Things like styling, lighting, and how much direction the photographer actually gives seem to change everything. I started digging into what does a fashion photographer do just to understand where their role starts and ends, and it made me question how much I should be managing myself. Not sure if I’m overcomplicating this or if it’s normal for a first shoot. For those who’ve done it, what caught you off guard the first time?
