Getting ready for a Wedding

One of Mark's best friends is getting married this weekend and I have nothing to wear.  What else is new right?  Well this is going to be one of the most unique weddings I have ever attended.  They are getting married at a baseball stadium.  They are saying their vows on home plate.  The bride and groom are both in to sports really big so this is really not unusual for them.  It is unusual for me.  We are going to be sitting outside in the cold for the ceremony and then inside the club floor of the stadium for the reception.  So what do I wear?  Mark said I could bring a stadium blanket to keep me warm and nobody would say anything.   Oh, here is the other cool thing.  The groomsmen all get to go on the field and play ball before the wedding and then they are getting dressed in the locker room .  This is probably the only wedding Mark has been excited about attending and being a part of, including our own.   He hates all the getting dressed up hulabaloo.   Mark's brother is going to be watching the kids for us, poor guy.   Oh, and the reception has a casino night theme.  I am so excited but, I still have nothing to wear.
