There are alot of great skin creators out there. whats best for one person isnt going to necessarily be best for another. it all depends on your personal taste and to a large extent the shape of your avatar. However you can never go wrong with LAQ ! i think just about everyone has at least one of thier skins. Another great one is Baiastice, they come with lots of options like eyebrows, cleavage enhancement, teeth and freckle layers ! curio, and tuli are also worth a look if you perfer a less shiny look.
