Preview Items in the Trading Post is on it's way into the game. Nice feature! Only thing missing now is the inspect feature. :)
Try before you buy! You’ll have the ability to preview items in the Trading Post before you buy them. Simply right-click an item icon and select “Preview” to see the item equipped on your character. Check out how a weapon looks by itself, how it looks when sheathed, and how it looks when wielded by your character.
