A sentence that describes the beauty of a woman…..?

I have encountered a sentence that describes the beauty of a woman:
"I will say this for Greg: he knew his women. Jane was stunning. Besides going in and out – and then some – in all the right places, she had the most vivid blue eyes, hair the colour of late summer straw, skin that shone with health and a soft, sibilant voice that seemed to enfold you in a secret cocoon, as if you and she were the only people in the world." And Jane is a spy…..
I can't catch the first part of the sentence: "Besides going in and out – and then some – in all the right places…" What does it mean by saying this…?
