So, having created my character and all, sometimes I like to see what he looks like, and how different clothes and weapons look like on him, but I can't seem to do a 360° camera tour around him, or even see him from any other angle than behind. Which means that spending time on creating a face is pretty useless.

In TES: Oblivion there was a specific button that let you switch over and see your character from the front (not just the 3rd person view also available in FNV), but I can't find it here. Does anybody know of a way to see this in-game?

What system are you on? On Xbox it is the LB

PC.

-oops didn't read the whole OP-

Console perhaps? Still uses the same game engine.

Or do you mean, hold the 3rd person view key and spin your mouse around?

It's the same button that switches between first and third. When in third, just hold it down and move the camera.
