Even though I’m not Mormon, I’ve bought many things from Dressed in White. They have the prettiest hankie envelopes that are just perfect for keeping precious things like old letters or pressed flowers. The white dresses and suits are perfect for a more-casual wedding attire.
There is a difference in Mormonism between Temple undergarments, and Temple Clothing.
This is a picture of Temple Clothing. http://www.concernedchristians.org/images/he2lg.jpg It consists of white dress, (or slacks, pants and tie, vail, apron, sash, white shoes etc. These are worn inside the Temple to perform ordinances. Mormons are most often buried in Temple Clothing.
Garments are underwear and are worn daily by active LDS. FR will not allow a link to garments, but basically they are underwear....you’ll have to google it go to http://images.google.com/ and type in temple garments.
