Q:
Need Transmutation Help
I’m not aware of any way to ‘recover’ from a situation where you might accidentally have selected the wrong cosmetic look for the piece of armor.
I guess another argument for creating a system that works more like dyes. Any time you use a transmutation stone on a piece of armor, both piece’s ‘look’ become ‘memorized’ like a dye, which you can apply whenever you want later. Whether they choose at that point to make us burn trans stones/crystals after that point to ‘only’ apply a look to a piece of armor (since no stats would be transmitted from a memorized look) is entirely up to their marketing department at that point.
But it would seem to solve the problem where you spend a lot of real or in game money and accidentally select the wrong item as the ‘look’. I can’t imagine how I’d feel if I had accidentally used the wrong look transmuting a T3 chest piece to something at 30g a piece. 
Lack of some of these fundamental administrative restoration processes is a bit frustrating this far into the life cycle. I sincerely hope you get a better answer than this one, which while better than nothing, isn’t a very good one.
As far as I know, no way to turn back transmutations. If you’re sure you selected the krytan skin look when transmuting and is showing your old skin, try to relog. I transmuted on my mesmer the starter harlequin mask look into a new piece of head armor I got (a hood) and seems the process glitched and showed both armors at the same time (looked kinda nice, a hood with the clown mask under it), but asking other people around they could only see the harlequin mask, relogging fixed the issue.
Maybe that’s what’s happening if you’re sure you did the transmutation right, maybe (hoping) both armors are showing but the new one is bulkier and hiding the krytan one and a relog should fix it. Otherwise I’d say resubmit the ticket specifying that you lost the skin piece in a transmuting accident and that you would like a way to recover it.
wrapped up in some crazy ritualist hoo-ha from Cantha.
A real grab bag of ‘you can’t hurt me. They’re called Guardians.
nope its showing just chest armor but it has the stats of the skinned armor i had befor
