Colors, Attire, Location, you name it I have changed it all numerous times so don't worry I think we all go through it. I have even changed my wedding party members !! (Not because I am cruel, 2 bridesmaids just couldn't make the trip) I am still unsure about my wedding dress I have already purchased thats hanging in my Grandmothers closet. Good luck with all your planning and trust me, you are not alone in feeling this way.
