There does seem to be lots of restrictions to it. And I'm not sure why. SWTOR has the best outiftter system I've seen in an MMO. You create tabs on your character profile, make whatever kind of outfit you want, save it, done. You can apply any look you want to at any time, regardless of where you are or what you're doing. There's no restrictions. And you never have to worry about a new item overriding your look. Once you apply an outfit, it's active until you change it, regardless of what your character actually has on.

It's super weird to me that other MMOs don't follow suit.
