Not new player, but this has bugging me for a while and some new players might have the same issue, so...

Some weapons can't be "glammed"(?) in the glamour dresser. I'm above their level, it's the correct job (of course!), but they're marked with a red cross.

This happened before with some GNB weapons and now I'm leveling a RDM and same thing happens. I'm currently level 55 and I can't use Guespiere (lvl 53) neither Martial Foil (lvl 51). There is nothing in the weapons that says it cannot be used as glamour.

Please advise.
