Here's a straightforward druid outfit.
I find the Recollection Gauntlets work tremendously well with the Y'ffre's Will set. The Icereach Coven helm is just cool. Pants are down to personal preference and options, definitely don't have to go Frandar's Tribute Guards here. Belt options include Nantharion's Royal Girdle.
I used a variety of Browns to make certain things pop and match. Wyrd Tree Green is really a must-have.
