In case you want a nude photosession, make sure you do not have an excessive make up. Such make up may significantly differentiate colour of your face from colour of your body, which will look not attractive at all. Therefore, please do not apply any make up before the photosession without approval from my side. Also, we might want to apply oil or water on your body, therefore any make up shall be agreed in advance.
Do not wear any compressive dresses or underwear. In at least one hour before photosession, you are strongly recommended to reject from such compressive dresses at all, including bra and panties. Upon your arrival to photostudio, you are recommended to immediately take of all clothes and change it to a gown or other free dress. Please note that traces from compressive clothing may remain on your body for 30-40 minutes.
No need to say, but you have to remove all unnecessary hairs from your body. Please do it in a common way, which will not irritate your skin. Irritated skin sometimes can be corrected in Photoshop, but any corrections do not make photography better. And sometimes corrections may be very complicated and expensive.
