To me as well but poeople are so different. I am 5’4" and 165lbs (75kg) now, should lose a lot of fat but someone else may be perfect with this weight (that’s probably the top for a woman with this height…? lots of muscles have to be involved :D) and some people just can’t hold to even 125 lbs (my near ideal weight unless I get more muscles?) for some reason but many girls are more fragile to me anyway, smaller hips, boobs, whatnot, or just less muscles so 104 is probably quite slim for them but nothing alarming yet…
Once I was 62kg, my belly looked to me just as fatty as at 80kg (it was so bad as I never could go lower, almost never was below 69kg and all my efforts did little to my main problem area). It was a tad smaller but I lose fat from everywhere else first… And I am not particularly muscular. Could be worse but still, nope.
I probably wouldn’t look bad at 48kg but as I never was even remotely that slim, I don’t know, I just guess from my 62kg self. But I don’t want to have so little muscles. My build is better with a somewhat bigger weight and I want as much muscles I can have naturally (and that’s very little being a 45 years old lazy woman). But that’s me.
Oh, people told me at 69kg that I don’t need to lose more fat… People here are fine with chubbiness too much - and black clothes hide a lot. It’s still quite obvious if one has a thick waist, though… A small belly roll is one thing (my SO has it when he is 2+ kg more than his ideal weight), nearly 20 kg extra fat, most at the waist-hip-thigh area is quite visible…
In the end, we just can’t tell things seeing only numbers. We can tell if it’s impossible to be okay at some extreme weight but between those extremes… I don’t care about my weight at all, just that how I look. My SO looked thin enough at 56kg (my probably “ideal” weight now, 124lbs. he is a male and 5’9"/176cm. couldn’t stay at that weight without starving though) when he was young without proper muscles. Now he looks good at 63kg (only muscular legs, nothing else)… And as we know, he could look great above 80kg with big and still natural muscles… 90kg probably would be fine then as we both prefer a nice smoothed look, not the hard to keep dry one. And it’s just muscles, the person is the same, the same skeleton and everything.
