Conquest of the Horde

I've been searching, and searching, and searching... I couldn't find anything. Maybe you guys could suggest any suit for a widow? I imagine it to be fully black and humble. I would require a hat, but thats' no problem - I can get them in Shatterspear. What I wonder about is where to get a proper black dress/robe, black gloves and black elegant shoes? I would appreciate your help on this one.

For the robe and gloves, I suggest:

[item]2800[/item]
[item]1314[/item]

For the boots, just by some recruit's boots at Shatterspear, near the Frills vendor.

The gloves are from an elite Ghoul in Westfall.
Not sure about the robes.

But you should really explore the auction house, there are loads of items on there.
