Oh, how exciting, you’re going to look absolutely stunning! After the amount of investment in this thread, there will surely be interest in seeing the finished article - perhaps your plus 1 could take along a camera to take some snaps of you throughout the day so you can show us all afterwards? Please please please.
Also, weddings are often an awfully long day. Don’t forget to take along some snacks to keep your energy levels high. IME cake is excellent for keeping sugar levels up but I imagine you’ll need to take along a couple or three tiers of it as there’ll probs be guests who won’t have remembered to bring their own, so I imagine you’ll end up sharing. So take a decent cake knife, too. Sugared almonds are also a good option.
