I recently discovered this qualifying technique while talking to one of my schoolgirl friends.
So here we were walking together on campus having a conversation (after a DHV story) when I out of the blue say, "You know what? I feel 2 inches taller without my backpack."
She'll say something like "Oh, how so?"
Then I say, "Well wearing a heavy backpack forces me to slouch, that way I have better balance; but it's become a bad habit so I try to correct my posture when I'm not wearing a backpack. I guess that's why I find it attractive when women have great posture."
Heres the good part, right after you say that all of a sudden slightly distance yourself from her and just look her up and down, grin/smile maybe even shake your head as in saying "never mind" then turn back to how you were walking but don't say anything about it.
If you see her out of your peripheral vision trying to correct her body posture, or if she asks for your opinion on her posture, it's mission accomplished, she's qualifying
