I personally am a big fan of masks, particularly eye masks and masquerade style masks.
There are very few of these items and the ones that exist are very limited in their glamour usage as they are class specific or undyeable.
I would love to have more of these available as simple glamour items that are dyeable.
An excellent start would be to make the Legionary Visor dyeable and maybe create a new glamour item using the mask part of the Saurian Bandana of Striking.
