When a bride tells me that she is shopping for a wedding dress for her second wedding I can generally point them in the right direction. Usually a second-time bride wants something simple and understated; there are many great ways to accomplish this without wearing a boring dress or looking matronly.
Personal opinion: Just because it is a second wedding there is no reason that you can’t wear a beautiful and fancy wedding dress, you just need to choose a more sophisticated style. For instance, the dress below is definitely in style but is a little more covered up and a very classic look.
Another point to take into consideration when shopping for your second wedding dress is what is the atmosphere of your wedding? If you are getting married on a beach or in a park you would still want something more manageable and light weight. A great option for this is a light lace or chiffon wedding dress. See below.
