Max AL (Armor Level) for Elementalists is 60, since they're casters. Front-line warriors have the highest AL at 80, while most everyone else is either 70 (Rangers, Dervishes, Assassins) or 60.
Have a look at GuildWiki in the Armor section. It has pictures of all the different armors (as well as where to get them!), so see if you like any of them before committing to dying it, since you can't recover dye. :s
