I once stole something but I don't know who it belonged to so how do I seek forgiveness for it?

I once stole a piece of clothing in the hostel. I don't know who did it belong to. I don't know the owner. It's been years now. I have realized my sin and have repented to God. Cried and promised never to do such thing again. But since it's transgression against another human being so how do I fix it? I don't know the person. And there's no way I can find them. Is there anyway to compensate for it?
