Keep cool, keep calm.
This is easier said than done but the calmer you feel before you walk down the aisle, the better. Always remember that the people who are there for you at your wedding are people that love you and support you. It’s easy to forget this as you’re about to enter the ceremony, but as soon as you realise that your husband-to-be and your family and friends are in the crowd filled with love, it’s a little easier to not freak out.
If you’re still feeling stressed out, have a glass of champagne or some rescue drops and sit in a room alone for five or ten minutes before you leave your ready room. This gives you a moment to recompose, as lots of people around you can often add to the stress levels.
And enjoy your moment! :)
