There are so many different discussions and viewpoints online about modesty and everyone seems to have their own opinion on the matter. Because we sell modest wedding gowns we deal with the topic of modesty a lot and we have realized that everyone has their own idea of what being modest means. Because we work with several different wedding dress designers, they too have their own opinion of what a modest wedding gown should be like. Some designers have very conservative necklines and sleeve lengths while others tend to not be as strict.
In order to follow the LDS Temple guidelines for modest dresses we try to work closely with our designers in order to make our dresses appropriate for LDS Temples. Each LDS Temple is slightly different on what they will let a bride wear to be sealed (married) in. The general guidelines can be viewed here and are as follows:
Wedding Dresses: Brides may wear their wedding dresses through the temple if these dresses meet accepted standards: white, high-neck or provided with a dickie, wrist-length sleeves, long skirt length. Trains are not recommended and hence should be detachable. Large hoop dresses are generally not recommended either, so the hoop should be detachable if your dress has one. Incidentally, there are many shades of white, so do not be too concerned about the shade, as long as it is white. All temples have white dresses that are satisfactory for a temple sealing in case you do not have your own wedding dress. Ask the temple matron about this, if it applies.
As you can tell from these guidelines, most modest wedding dresses don’t have all of these criteria, nor do most brides want full length sleeves and detachable trains. Because of this, we like to recommend that our brides, who are getting sealed in the Temple, either wear a long-sleeved leotard under their dress and make sure to have their train busseled, or wear their regular temple dress for the ceremony and change into their wedding gown afterward (many brides are choosing this option so they can have an ivory wedding gown, which tends to photograph better and be more flattering on most skin tones). Be sure to check with your specific temple matron on what they will and will not allow the bride to wear for the ceremony.
