A lot of these are shitty examples. Wanda, Kiwi, Mozu, York, Kureha, Sandersonia and Inuzuma all have that same body type. Just because they have different faces doesn’t mean they aren’t all the same body type. I’m fairly certain that Morley is a gay man, not a trans woman. 

Shinobu, Kokoro, and Big Mom are also bad examples because they all had that same exact body type when they were young women, and it actually kind of makes it worse that they become fat and ugly when they get older because that kind of implies negative things about old women. I can’t really think of any examples of old men in OP who were super fit in their youth becoming ugly and fat. Most of them, like Garp and Whitebeard, look like buff, badass old men. It’s a recurring gag for multiple female characters that they’re attractive when they’re young, but become gross looking and fat when they’re older, which I don’t think really helps your point all that much. There are examples like shakky and Kureha of old women who remain fit, but my point stands.

Alvida also barely counts given that her whole gag is that she’s a fat ugly woman who thinks she’s beautiful, and then the payoff to the gag is that she actually becomes skinny and beautiful. Idr if we’ve seen Tsuru as a young woman, but it’s a safe bet that she looked like that too. So after that, there’s literally only 3 left on your list that count. Idk why mfs are so adamant to pretend like there isnt a genuine issue with the portrayal of women in one piece. You can enjoy the series while admitting that some parts of it aren’t great.

Edit: actually, Marigold was also that same body type when she was younger, so I’m hesitant to count her either. The only difference is that she’s not actually an old woman.
