Outfitter allows you to create multiple outfits and equip them with a click of your mouse. You can layer outfits, create outfits optimized for a particular attribute (ie, fire resist or maximum defense), and have outfits which automatically equip.

Automatic outfits include riding, Argent Dawn (plaguelands), battlegrounds, and class-specific automatic outfits like shadowform, stealth, warrior stances and druid shapeshifting.
