Whatever your face shape, ensure that your wedding day hair compliments what you have. If you have a rounder face, a hairstyle with some volume and height is recommended. If you have a more square face, you might want a hairstyle that is layered. Hairstyles that is wispy in a romantic way or away from your face works as well. If you have a heart-shaped face you might want to go with a hairstyle where you have a lock of hair across your brow.
Remember that whatever hairstyles you have in mind, you should always organize a trial run with your hairstylist. This allows you to gauge how much time the style will take and more importantly, whether the style suits you. What's more, your stylist should be able to advise you and give you ideas which helps to make you decision easier.
