I was stood on the platform (in drab) waiting for a train and observed a 20'ish GG in a skirt and 2" ankle boots on the opposite platform. She was stood with her right leg crossed over the left, right foot turned turned to the right.
It's one of those things you see, or the mirror image, regularly if you look for it. I've tried it and I can't say it's particularly a more comfortable stance than just legs parallel. So is it one of those learned behaviours GG's have, a mannerism we need to add to our data bank of femme gestures or just a more comfortable way for standing in heels?
