I loved the way my bms looked in their matching dresses. I think they all look hot and while matching may not be the way to go for every one, I am glad they picked it.
I don't mind when a couple registers for ridiculous registry items (meaning high priced). If you don't want to spend that, then don't. I would prefer people to register for outrageous pillows they will actual use in their married home together than a facial on their honeymoon. In fact, I think it is more ridiculous when people register for things like paper towels than when they register for a high end vacuum.
Now you go...
