The garment that you are given in the temple is mostly for modesty; but we joke here about them being "magical" but there is a promise that if you're faithful, they'll protect you physically.
If someone cuts off the sleeves of the garments so they can wear a summer dress of top, they have rendered the oath/magic useless so they may just as well go without.

Thanks for the quick replies. I'm thinking about for men in particular. There is a group of faculty at my daughter's school who all seem to be LDS. The school and surrounding area have a strong LDS presence. I've noticed quite a few faculty members at athletic events clearly have garments on under their sporty school shirts (for example, temps in the 90's, but there are clearly garments under their lightweight shirts). But there is one guy who seems to "fit in" with the rest (crew cut, wholesome talk all the time, etc), but he always has the tank-top on under everything. He's normally wearing a white shirt and tie, and the tank top shows through like it's illuminated, and when he wears those lighter weight kind of shirts, it's so heavy that I can still make out the tank top going over the shoulders and across his back. Is it possible he's LDS but not wearing garments yet?
Yes, possible. Finding out whether he served a mission or not would be the oblique way to figure out if he's been through the temple. But asking straight up if he has been through the endowment ceremony yet would answer it definitively.
Some get endowed but never serve missions, some don't serve missions and never go through the temple until marriage, some get a civil marriage because they have an asshole bishop who never declared them "worthy" to go to the temple, and some are "sinners" who are honest enough to confess to their bishop something mundane like masturbation which really can keep an otherwise saintly good person out of the temple.
They're the modern day equivalent of a chastity belt, in that no first time or extramarital encounter will probably go very well because the LDS person is thinking "like OMGosh," am I really going to go through with this, break my temple covenants thereby placing myself in the hands of El Diablo? If the encounter is with a non LDS person, the garments acts as a natural libido inhibitor, thereby providing "protection."
