Padded fursuits, how do you do it?

I'm really wanting a bear fursuit or a monster that require quite a bit of body padding. I just don't know where to start though. Do you glue the padding on the dive suit? If so how do you wash your suit? I don't want to be cute and smelly. The padding is really just lower body padding, like legs, belly and butt.

I have no idea what to do....can anyone post some tips or even a tutorial? :(
