They don't suit everyone. If a woman has hips, i.e. not fairly straight up and down or just quite skinny, most jumpsuits aren't that flattering. Comfortable, yes, flattering, no.
I have a work colleague that's a size 6 and quite short, she wears fun jumpsuits in the summer and looks ace in them, quite elegant. Another colleague of mine wears baggy colourful dungarees and looks awesome. Flattering maybe not so much, but she's about the size of a 16-year-old, and wears a lot of childish clothing without having to think about fit and comfort too hard, most of what she wears fits deliberatey baggy.
I am tall and not particularly blessed with hips, I wear baggy boiler suits for a catwalk-y look and get a lot of compliments.
While jumpsuits can be super comfortable, they are not necessarily designed for a feminine figure. I love them for a WFH outfit due to comfort, but... I'd only wear certain ones outside the house.
Also, they're overrated because, when you use the loo...
