Guild Wars 2

So i think i am going to buy the Krytan gem armor but i am wondering one thing.
When i bought the armor, can i wear it at the same time as i wear any other actual armor but still have the looks of the Krytan.
Or do i have to “attach” the Krytan to one armor wich mean i would only have the Krytan looks when i use that specific armor.
Hope this thread is not to hard to understand.

It makes your existing gear look like Krytan armor. The stats will not change.

this armor works like the hall of monuments gear, you transmute pieces of your gear into this set.
