When you start to look for a wedding dress, make sure you take along someone whos opinion you trust. You will also need to go without any pre-conceived ideas about what you want. You may have always dreamed of walking up the aisle in a fairytale ball gown dress, whereas in reality, that style may not suit you at all, and it's actually an elegant empire line dress that makes you look fabulous.
Be open to recommendations made by the people who work in the dress shops; they have seen hundreds of brides, and have a good idea of what style will suit you. You certainly have nothing to lose by trying on what they suggest.
