AFAIK, those garments are only meant for use inside a temple. Hence the name, temple garment.![]()
WRONG. Completely and totally wrong. It's called a temple garment because after your "endowment ceremony," where you are officially brought into the temple and therefore allowed to be the in temple as a member, you are given your first "garments." These are worn at all times, day and night, throughout their entire life. They can only take it off when absolutely necessary, like swimming or having surgery.
