I felt the same about garmmys too. I've had several pair where the legs were as much as 4 inches different. I had one pair of shorts that was probably too short for church standards but if I picked exactly the right pair of garments they were covered just fine.
Ha-ha-ha! If Mormons were to wear the actual robes en route to the temple, they would probably be disfellowshipped!
You're right! A Mormon woman wearing a flour sack with frayed sleeves, slippers, and no jewelry would definitely be snubbed in Relief Society. How about a man dressed in polyester sweat pants a sheer tunic an apron, and a silly head-piece, wanting to take the Scouts on a camp-out?
