Long hair is definitely anti-jimiko but I wouldn't put short hair in the same tier as glasses and freckles.
"Secretly big boobed" is another jimiko trope but a dangerous one. It's important that she wears plain clothes and the boobs shouldn't be exposed.
But for me the third piece of the triforce (as in very powerful but shouldn't be combined with the other pieces) is eyebags.
