lol just let them be
on the other hand, as much as I am tired with all the silly "timeless" talk, I'd still say that a proper black tie (tux) is almost transcendental... it makes anyone look good and the uniformity leaves no room for peacocking. in that regards I do respect black tie as close to "timeless".
Yes, you're right. There is only one style of tuxedo, one universally accepted definition of "proper black-tie," and there is certainly only one objectively definite way to "look good."
