A few things strike me about this:
One, why is it that women's clothes sizes are disconnected from actual metrics? We poor men have to buy pants that have
Two, the fact that sizes are increasing in, well, size seems completely reasonable if the goal of the women's sizing system is to be relative to an 'average' woman - who has grown in the last few decades.
Finally, having clothes sized in an objective and not relative metric provides me an incentive to try and keep fit and trim. I absolutely hate having to buy pants in a bigger size than the ones they replace. So in this sense it is good for me as a consumer. But clothes manufacturers are in the business of trying to make consumers happy, so fudging on sizes seems a natural consequence. And thus I am led to wonder, are my size 32 pants, really 32?? Oh god, I hope so!
