Your points are good, however I would expect an Egyptologist who specialized in clothing to be aware of them. And they did use the loincloths to obtain the hip measurements. I don't recall what they used to get the chest measurement. For the waist measurement there was a type of clothing that was worn wrapped tightly around the torso area during rough chariot rides that they used for it.
I was rather afraid of the show being a basket case one, because all the commercials were things like "using evidence long ignored" but overall it was pretty good. I still do find the complete ommission of even Smenkhkare's name when the identity of the body in KV55 was being discussed rather odd. They kept comparing the skull and other features saying that this would be typical for a father and son to share these features and I kept saying or two brothers!
Anyway ... overall it was very good I thought.
