Costume Gears: Usable or Unusable in GVG areas?

[Keegan]

Personally don't care if you can use it in WoE and other PVPs, as I don't see how those gears being hidden would really change much. 70% of someones gear is already hidden not including cards (closer to 85% if you include cards), and many of the other slots are more important then headgear in PVP settings(ie. ghostring, marc, develing or gtb as examples). Besides even if you know what someone has carded in their headgear does not mean they don't have a second one (or even more) carded differently.
