Updos at weddings need to be sturdy and long-lasting. Its best to get a professional hair stylist to create a look for you, as they will have better tools and more experienced hands.
What you can do at home is experiment with different styles, so you know what to ask your stylist for. Work out what suits you and goes with your beautiful dress.
You might want your bridesmaids to have a simple updo hairstyle as well, so make sure to plan in enough time for them to go to the hair stylists too.
