My FI and I had our wedding bands custom made by a friend of his in another state - the same one who made my engagement ring. We sent him our ring sizes and he made the rings and is sending them to us. I want to try on the rings when they arrive to make sure that they are the right size for us instead of finding out at the wedding when we can't slip them on each other's fingers. However, I mentioned this to a family member who subsequently freaked out and proclaimed that it would unleash all sorts of bad luck on our wedding. Is this real? For the sake of superstition, (to which I am more susceptible than normal since marriages in my family don't tend to last), should we not try on the rings?
