Obviously with legs you don't have to bother keeping the pores as you, most of the time, would do when retouching a face, but you do wanna keep some texture. I was wondering if anyone would give me some good tips on how to make legs look ultra smooth, while still keeping the texture of skin intact? My description may be a little vague, so I looked up an example of what I mean.

If you look at Britney's legs, you'll notice that the surface looks smooth, but you can still see that they are real legs (obviously not 'real' real, they did some massive thinning) as they still have the texture a leg normally has. Obviously the lights and shadows have been exaggerated with some nice dodge & burn, but I'm sure that's not the only thing that contributed to the smooth look, right?
