as you know can change sex, you can change the dress and the changes are visible after the tab character. Is it possible to change the image of arms on the character? thanks for your reply 
Short answer: You can’t.
The weapon display in the guild roster has been broken since February if I’m not mistaken.
Don’t know why it’s taking this long to fix, but I’m sure they’ll get around to it someday.
thank you very much for your reply.
for now subject to close
