How to make X vocation only wear X outfit?

[tony adamantium]

For example:
Knights can only wear Barbarian and Warrior outfit, paladins wear hunter outfit etc.. see what I mean?
I don't know if this is possible but if you guys can help me I would appreciate it!

You can use quest in outfits.xml and then add the storage for every voc in login.lua.
