It's lovely, OP, and if you can wear yellow it will be much more flattering than a bright white dress. Do you know whether you have a warm, yellow skin tone or are you cooler blue-toned? You can either experiment, draping your face with a pale warm yellow scarf and seeing if it suits you, or ask someone at a make-up counter to test you. Just saying this because if the dress is definitely pale yellow and you are a blue-based winter it may may not flatter you and could make you look a little sallow. Hope you're yellow-toned!
