Whenever you hover over one of the new Plumed Caps, or the Grand Toppers, you can't quite see the entire thing. This also is a problem with inspecting other players, or Previewing the item on the Auction House. Really the only way to see the two items in their full glory, is to equip them, or see them on another player.
Not particularly urgent, but could you change this? Just, make it so the entire thing can be seen before equipping/attaching.
Makes sense.
