Fat girls and tasteful nude photos?

I'm a big girl, but I still have some great qualities. I'd like to take tasteful nude pictures, but I'm having issues on how to go about posing to hide my less attractive qualities. This will all be done at home, so no professional lighting, no professional photographer...I want to look beautiful, enticing, but not quite ographic...think tastefully (Playboy, not Hustler). Can anyone help with poses, lighting, any kind of advice? Thanks guys.
