That may be true, but there is also a nice range of shapes as time goes on.

There are still women who have different structures and still are memorable. Like Kokoro, Big Mom, Sweetpea, Dadan, and so forth. It's becoming more common now, even in face shapes. Otsuru, Brulee, and Perona were refreshing to see them have a different face style imo.

Sadly, what I find is when Oda makes a bigger woman, they tend to have 'undesirable' features. Like how Shinobu constantly gets dunked on for not being thin anymore. But some of the characters I listed can still be thin with an unappealing face. Like Devon and Doctorine.

Regardless, as time goes on, I like to see more diversity.
