One of those is; Her legs went all the way up.
It's an idiom. You can't make sense of an idiom from the actual words used.

Idioms exist in every language. They are words or phrases that aren't meant to be taken literally. For example, if you say someone has "cold feet," it doesn't mean their toes are actually cold. Rather, it means they're nervous about something.
Idioms can't be deduced merely by studying the words in the phrase. If taken literally, you would think that someone with cold feet hasโฆ cold feet. But, after living with a certain group of people for a period of time, you'll start to pick up their expressions. Let's explore some idiom examples in American everyday language, international language, and the language of the arts.
In this particular case (Her legs went all the way up), it's a reference to a woman having relatively long legs in proportion to her torso.
I can understand this sort of thing, I have disproportionately short legs. Standing next to my brother he's a couple of inches taller than I am. But if we sit next to each other on identical chairs, I'm taller than he is.
P.S. Lincoln is reputed to have said in response to a question about how long a man's legs should be: Long enough to reach the ground.
