This always makes me laugh.

For fun we extrapolated from one novel in the mid-series just how many lines exactly are dealing with the "redundant body language" or the descriptions of clothes in one novel.

There was material for about a page in TFOH, which likely means there's something between one to two chapters' worth of it in the whole series, if it was all regrouped, perhaps 3 chapters to account for the books with a lot of Elayne and her wardrobe. Given the number of chapters, it's really a drop in the ocean.

The length of these descriptions is part of the problem, but not the way people usually think: Jordan made them too short and too formulaic, so they rapidly become boring and repetitive, it's not because he described the clothes in too many details.
