Deleted character
Arena net will not restore character when someone or someone friend in house delete it. They only do restore if account get hacked and that is full account roll back. But you did not get hacked so you are out of luck with that. The armor skin should still be in you wardrobe if you use it on that character like you say.
Should maybe be more careful what kind of “friend” you keep in you house when you sleep.

Qugi is correct. They don’t do restorations for non hacked accounts and your armor is in your wardrobe.
ANet may give it to you.
That skin should be in your wardrobe even if the character got deleted.

Aright thanks for the info, sadly the “costume” is not a wardrobe thing.
The skins were items still. EX piece for piece like the old times
I should… But he dident knew it had items i spent real money to get on that character :/
The CS Team often replaces Gem Store items lost due to deleted characters. You can contact the Team, and inquire. Nothing ventured, nothing gained.
Good luck.
