Modern day LDS (Mormon) garments are t-shirt and knee Length. They are only worn by the members that have gone through the LDS Temple. Once a member has gone through the temple they are given these garments which are considered sacred. They are not talked about much publicly even to other members of the church other than the fact that you are supposed to wear them at all times, and that they should never show to the public.
The fabrics do vary... I have seen cotton and silk like garments. ( I was married to a Mormon man who wore the garments) They do have markings on them which are also said to be sacred and carry some form of symbolism on them. --- These markings are also NEVER talked about.. so if you find more information on them please let me know.
There are no words printed on them, and the markings are small stitches on certain area's of the body.
The garments are always white, men and women both wear them after having gone through the temple. They also are buried in them.

Garments include clothing and accessories such as hats, gloves, shoes and socks. There are handmade products which command a high price as they take a long time to make. However, custom work is requested by people with more money or who have specific needs. Most garment manufacturing utilizes a pattern first and then the cutters cut the parts with special tools in quantity. Sewers put the parts together and voila! You get a finished garment ready to ship. Usually samples are made and shown before quantities of styles are made. Fabrics are sometimes dyed by the manufacturer or purchased as is. Threads, tassels, buttons, frogs and other adornments add up to a good or bad product. The label must include directions for washing or cleaning. Children's garments have flammable requirements. Zippers can be difficult to sew in properly and some zippers are better than others. Buttons require just the right hole sizing. Dyes of different fabric lots are slightly different. Sewing machines have different attachments for making seams, monogramming, etc. and should be studied for you to get the desired effect. Hats, gloves and socks are other specialty garments that require knowledge and studying because of its complications.
