For once Roy is right. As human beings, we find enormous comfort in knowing what is ahead of us. This is why the first time you have to speak in public you are very nervous, the 50th time you do it, it’s fine and feels normal. I’m not saying you should get married 50 times though!
I’m saying you should plan and rehearse the morning routine.
The week before the wedding you have all the bits you need for the morning and put them all in one place. Check that it’s all there.
With the help of the person who will help you in the dress, get in the dress, fully! Not just halfway and say it’s grand, button every button, if there’s a belt, put it on. If the your helper will be wearing long nails, make sure she’s comfortable doing buttons with these on. A great tool to have is a crochet to pull the little button strings. Get one.
Put the shoes on and walk, how does it feels? Sit down, stand up everything should feel comfortable. If not, you have a few days to sort it out. No panic.
The night before the wedding, lay down all the bits and hang the dress in the room you will be getting ready. Tidy it up too, no clutter! It’s bad in photos and you don’t want that do you?
