What do the sewn-on inscriptions on the LDS undershirts stand for?

Answer 1

I know that I will sound like a crazy woman.

Our garments remind us of sacred covenants that we make in the temple. The markings have special meanings. Because of the sacredness of the temple- I really don't think this is the place to discuss this.

When did it become appropriate to go around asking people about their underwear anyway?

Answer 2

I've never seen them, can you post a link to a picture?

I was a Freemason until I became an atheist so I may be able to spread some light on it.

Edit:
Thanks Meat bot!
Yes, they are a square and compass. I believe the the lower symbol on the leg is a level (if it is a symbol).

Edit:
Interesting link that phrog provided. I ran thought it and while the author makes some good points, I would saw that given Smith was a mason, and there is a high correlation of many of the symbols, you can not dismiss the possibility of influence.
And yes, many of the rituals, layouts and handshakes are taken directly from Freemasonry. I believe the current handshake has been modified slightly. The quote from Genesis stands out, not sure if it really used the word apron. Not only that but the Square and Compass are very significant to a Mason and would not lightly be used in any other context.

Answer 3

You are going to get answers indicating that they were taken from the masons, as Smith, Young, and many other early mormons were masons. In the state of Utah, many of the older building and even the temples have masonic markings on them, as was a common practice by masons - who built them. There is however, conflicting information regarding this. I could give you these answers myself, but it is better if you read them from someone who functions in both worlds.

Here is a link for an answer from an LDS mason.

Answer 4

It's a carryover from Freemasonry. Joe Smith was a Mason and incorporated Masonic stuff into Mormonism. They are Masonic symbols. The "V" is a "compass" and the reverse "L" is a "square".

By the way, until 1923 they were crotchless! That's hot.
