Guild Wars 2

I was wondering if there was any way of obtaining a skin form a different order than the one I have already joined. There is one skin I need in order to complete my look but I can seem to buy it because I did the wrong order.

Yes, you can.
You will need another character that joined this particular order.
This character will buy the skin and then transmute it to a white or blue armor piece (one that will not be soul-bound like green or above), keep in mind to choose the order skin whilst transmuting.
It becomes account-bound.
There you go!

Did that work for you or anyone?

I was able to do this just a while ago, using a level 18 white.

Any change for this feature with the latest patches? Is it still possible to trasmute order armors?

Not sure about order armours but I made my shield skin that was soulbound to 1 char soulbound to a different one by transmuting it onto a white then onto char no.2s shield.

wonder if this trick would work with race armors.

No, it doesn’t work with race armours as they are designed for the specific body models of that race. I think I remember reading that you could do it just after launch but that the armour didn’t look right or didn’t appear at all when placed on a character of different race.
