You've got the address all mapped out. Your lingerie is stowed away in the trunk and you've come up with a plan to explain why you're going to be gone for the next 4-5 hours.
Yet, you're still NERVOUS. You tossed and turned the night before. "Will she photoshop my cellulite? I hope she knows how to hide my thunder thighs." Wake up before the alarm goes off. Stress about the under eye circles you now have. "Maybe the make-up artist can cover them."
If you want to know what it's really like to do a boudoir session from a client's perspective, now you can hear it for yourself. It's also captioned for you in case you're not in a position to listen with the sound on.
