Yes. Because there is nothing esoteric about knowing how people dressed if you are going to talk about their lives.

No. Just honest and at least slightly competent.
Judgements of competence and honesty are subjective; we can all fail to distribute them fairly (especially when it comes to ourselves).
Rarely, when it comes to a history of an entire culture that spans hundreds of years and thousands of miles, can we find one perspective that describes a universal "truth."
All we have are shades of approximation.
That doesn't mean that there's no value in that approximation, it just means that we have to be a little patient with each other while each of our generalizations don't necessarily conform to the ineffable complexity of such a large group of people over such a large area over such a large timespan.
"Perfect is the enemy of good."
