eli5 Why aren’t women’s clothes sized by measurements like men’?

Question

I can understand uniquely shaped clothes (halter tops, etc) but why not pants, skirts, suits, etc?

(woman here) I absolutely hate the sizing for women’s pants; it is a constant roll of the dice.

I DO realize that women’s pant sizes probably shouldn’t be limited to length + waist, but should be length + hips + waist because the fit requirements are so different for women. That would be amazing if we could even manage to get brands to follow the male standard. I’d settle for it.
