Thanks Lures, for the link. 
I copy and paste here our official info from that webpage:
Preview Items in the Trading Post — 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.
Since this question is solved, we proceed to close the thread.
