Like the previous people have already posted, your armor will look alot like like a rouge and later depending on how you enchant it depends on your abilities. My druid was the 3rd or 4th toon i stated to actually level, so I had a bit of gold, I bought two sets of armor, for the lower levels, I had pretty much everything 'of the Monkey' for melee DPS, and for tanking everything was 'of the Bear', I cant ever decide what spec to go so I also have a set for Balance and Resto. Later as you level, especially in the outland I got almost everything 'of the Bandit', but still kept up with my DPS armor, then get your PvP gear. So yeah you should have at least two sets to be a good versatile druid.
