Taping

My tape comes tomorrow and i’m absolutely BRAND new to taping. I’ve never measured my chest till a few days ago and google gave me a bunch of different results but I know for sure i’m atleast a D cup. I was just wondering what’s the best way to tape, like should I be leaning back, laying down, should I tape straight to the side or tape at a lower angle (idk how to explain it), ect ect. Any advice is appreciated :)
