Shave your privates or if you do ,remember what it looked like when you saw it for the first time?
It looks really good once you are used to it and is so much nicer in the house, lol. I'm not sure what length you are asking about though. In most cases the body is smooth with the head and the tail left longer or the head blended in. Here's one dog I found. You can look for pictures of border collie's or australian shepherds with haircuts to try and find more.
