You may always have paracetamol in your purse, or some lip-balm in your bag, but for the morning of your wedding, I highly recommend packing an ‘Emergency Wedding Kit’ full of everything you could possibly need - just in case!
Here are the main items I would include:
Pain killers (Paracetamol/Ibuprofen/Calpol)
Clear nail varnish
Extra earring backs
What else would you put in yours?
