I miss the highlander woad in GW1. With the roll out of the wardrobe, I think it would be pretty cool to have a Kilt, and be able to dye the tartan (too technically challenging?). Would be outstanding to be able to wear my clan’s colors (especially wielding a claymore!)
I would even go so far as having a fairly involved scavenger hunt across Tyria to get materials and have a tailor craft the item (including special dyes from chef, so cross crafting fun). I would hope that it could be for light, medium, or heavy armors… giving the tailor some cross profession use… (then follow on with a leather worker and armorer outfits for the different professions).
Something that requires some time for casual player that does not have a ton of money to buy or time to farm mats (for ascended) or insane time and money and luck (for legendary)
