The WTS. has always stressed uniformity in modesty regarding dress and appearance toward its members, as to appeal to the outside general public.
Kind of like a enforced and regulated dress code within a business environment.
I would normally agree with this, and do in general. In this case they kind of lose me when they start talking about "tight pants".
If they want total uniformity, then I say go full steam ahead with those blue and white uniforms recently posted for every JW, along with a visit to a WTS approved tailor for a personal fitting. This way you solve all tight pants and skirt length issues in one swoop. Not sure how you solve the overly effeminate body language of some of the brothers though.
To be fair the letter does emphasise the word extreme.
I've seen some pretty extreme effeminate body language by a few top tier, convention-talk-giving brothers in my time. If I had not known them in a JW setting and known their wife and kids....
just sayin
