I cross at my thigh and cross at my ankles, sort of double cross. Keeps me close and secure and, I don't know but I sort of like guys looking at my legs

Don't do the double in knee high boots. Swing your legs out and do a thigh cross, let him look at your boots. Why do you think every girl in the restaurant cannot get her feet under the table.
Oh I remember. Flirting. I love it.
When he is fixated on your boots, bend forward so he can see your cleavage. Then act appropriately for how you want the night to develop.
Enjoy
