Blue.

As you all know by now, Katie and I have registered at Neiman's. MY FAVORITE COLOR IS BLUE. Katie doesn't have a favorite color. So make sure everything you buy is BLUE. It is very important that you follow these instructions, because I don't want to have to waste my time buying blue things. It IS my wedding afterall, and you need to get me what I want. Don't get crazy and start thinking you know better than me. And for god's sake don't buy anything pink. I'm sure you wish us all the best. Have fun shopping!
