This is subject to opinion, but I would like to add that according a book on tango by Pellicoro, he says that:
In the end, the lady always has the final say in how close the couple will dance, and an experienced man will always sense and respect this, regardless of the lady's level of experience."
Good point to note!
Some men are creepy and the woman right away by intuition knows if it is "funny business" or just plain dancing. When I know the man is up to no good, I set my personal space (it becomes open embrace) but if I feel comfortable and not threatened then I surrender to my dance partner and fall into place. The woman finds her "niche" so to speak, never look down. my face sort of faces his really close. I do not look past him because it then looks like I am dancing with someone else instead of him.
Agree indeed ... a woman knows a million miles away when a man is creepy. But those men do not last long.
I love it when a women knows how to do a real close embrace by the way, I think that is the way tango should be danced.
I think that style is "canyengue" . Look in YouTube classes of canyengue. And look I. YouTube many tango dancer, the master how they dance the milonguero close embrace like oscar casas or chino perico or Monica Paz.
As I've already said I prefer a closed embrace. Something y'all seem to be ignoring is the height of the partners. One of my favorite dance partners is 11 inches shorter than me. She loves it because she can wear outrages heels but she ain't ever going to reach my cheek. This is fine because while I do like dancing cheek to cheek I love it even more when my partner rests her head on my shoulder or chest.
