I’m not sure it’s possible, because the different parts of women’s bodies don’t tend to scale in relation to one another. There’s the waist-to-hip ratio, thigh circumference, breast size, width of shoulders, length of torso, length of legs – none of which have much to do with each other.

A woman can have size L shoulders, size XS breasts, size S waist, M hips, L thighs, long torso, and short legs. Another might have M shoulders, XL breasts, XXL waist, L hips, and M thighs, short torso, average length legs. And no retailer would bother making garments that account for every possible combination, because that wouldn’t be profitable. (This is why so many women with small chests and small ribcages are sold 32A bras that gap on top and ride up in back, when a properly-fitting bra would be a 28C – companies can make more money by selling less variety.)

Men, for the most part, have more similarities in their shapes and less variety in where excess adipose tissue settles. Also, as someone else pointed out, it’s more socially acceptable for men’s clothing to fit like a sack.

The solution, unfortunately, is alterations, either by hiring a seamstress or doing it oneself. (No judgment from me: I keep meaning to learn that skill but CBF to get a sewing machine when I might abandon the project.)

Dialup

How many people are going to still post death threats, character assassinations, or make racist or sexist comments.

Plenty! People like that aren’t ashamed. They’re proud to be in the group of people who actually count as human in their worldview.

is that something we would want?

The only effect would be to stifle everyone else. If everything you say online is tied to your real identity, many people would have to be the most bland, professional, worksona version of themselves to protect (a) their ability to earn income, and (b) their safety. People talking about their experiences with abortion would put themselves at risk of harassment, eviction, prosecution, and violence. Someone seeking support as they discern their gender identity is now outed to family, employers, people with social and/or economic power over them. When anyone from a marginalized group dares to post, it’ll be just like speaking in real life: if someone’s facts and tone are less than perfection, they (and the entire group which they’re assumed to represent) will be dismissed as intellectually inferior or too emotional.

Fisticuffs? Blade weapons? ….oh. Face to face meetings. (Insert scene from Office Space where that nerdy-looking guy is driving in rush hour traffic playing “Damn It Feels Good To Be A Gangster” like it’s his anthem)
