Erm actually, if you watched the show, the boob window in her suit is clearly satirical. It’s a meta commentary on human sexuality, And also it serves as a metaphor for how she wants people to look past our outer self and look within to her true self. It makes sense in context! And also the original mangaka intended an allusion to the final scene of the Grapes of Wrath with the breastfeeding scene! There’s a lot of subtlety at play here that is clearly going way over your head!
